Top-down alien shooter · particle-1

Let me check Phaser version.

Let me write the game. Phaser 3 likely. Check version string.

Phaser 3.80.1. Build a top-down arena shooter.

Design:
- Canvas 960x640 scale FIT, background dark.
- Procedural textures generated with Graphics -> generateTexture: player (triangle/ship), alien, bullet, particle maybe.
- Physics arcade.
- Player WASD movement, rotation toward pointer, fire on left mouse with cooldown.
- Aliens spawn in waves, move toward player via velocity each frame.
- Bullets damage aliens; contact damages player with invulnerability window.
- HUD: health, score, wave, controls. Use DOM overlay for HUD? Better use Phaser text but DOM overlay gives crisp controls. Requirement "Display controls on screen." Could use HTML overlay for HUD and game over. But game state is in Phaser. Simpler to draw HUD in Phaser with text, and game over overlay in Phaser too. But HTML overlay is fine if synced. I'll use Phaser text for HUD + controls, all self-contained in canvas. Restart button as Phaser interactive rectangle + text.

Need visible hit feedback: particle burst, screen flash, alien flash tint, small camera shake. Floating score text.

Arena: bounds with inner border, some decorative stars/nebula via graphics.

Waves: wave 1 with 5 aliens, speed ~70, count increases each wave, speed increases.

Player: health 100. Contact does damage (with cooldown per alien & player invuln ~0.6s). Also maybe player can be hit repeatedly. Enemy contact damages player then pushes enemy back slightly.

Shots: fire rate 150ms, bullet speed 700, damage 1; alien hp scales slightly? Keep 2 hits maybe, wave 1 hp 1? Let's use hp = 1 + floor(wave/3). Bullet damage 1.

Score: +10 per kill, wave clear bonus + wave*5.

Mouse aim: rotation to pointer world coordinates.

Firing: pointer down, hold to fire continuous.

Game over: physics pause, overlay with final score, Restart button. Restart resets everything.

Pause on game over: set state, disable update, maybe this.physics.pause() and stop player input.

Implementation details: use groups with classType? Simpler: bullets group physics, aliens group physics with custom data (hp). Use overlap for bullet-alien and player-alien.

Physics: arcade with world bounds. Player collides with bounds. Aliens collide with world bounds? Better they just move toward player, clamp within arena. Set bounce maybe. Aliens shouldn't leave arena: set collideWorldBounds true and bounce 1? That could make them jitter. They home, so angle toward player each update; set velocity from angle. Use world bounds collision with bounce 0.6? For homing, they'd be fine; just clamp positions manually.

Aim reticle at pointer: draw crosshair graphics following pointer. Good for feedback.

Procedural starfield: place dots in background layer.

Let's carefully code.

Textures:
- player texture 44x44: cyan triangle ship pointing right (rotation 0 = right). Draw with graphics: fillStyle 0x3ff5ff, triangle (40,22)-(8,4)-(8,40), hull line, cockpit.
- alien: purple/pink blob 36x36, circular with spikes / claws.
- bullet: 12x4 capsule yellow with glow.
- particle: small 4x4 circle white.
- reticle generated? Draw dynamically as graphics fixed to pointer.

Generate textures in create via make.graphics.

Use scene scale mode: Phaser.Scale.FIT with parent. Body background black, canvas centered.

HUD in Phaser: top bar with health bar graphics (redrawn each update), score text, wave text, controls text bottom-left small. Overlay game over: rectangle alpha .8 + texts + button.

Also wave banner "WAVE 1" flash.

Let me write code.

Key mechanics:
- Update loop: if state !== 'playing' return.
- Player movement: velocity from keys normalized * 260.
- Player rotation: Math.atan2(pointer.worldY - y, pointer.worldX - x).
- Fire: if pointer.isDown (leftButtonDown()) and time > nextFire → spawn bullet at player position offset 26 along rotation, velocity 700.
- Space also fires? Not required but nice; leave mouse.
- Bullets: lifetime, destroy when out of bounds (physics world bounds? set bullet body collideWorldBounds false, onWorldBounds? simpler: check in update and destroy if outside 20px margin).

Aliens:
- spawn from edges randomly outside? spawn inside near edges with margin 40, not too close to player (min distance 250). Choose side.
- Each has hp, speed base + wave*8 + random.
- update: angle to player, set velocity, slight wobble? straight homing.
- On hit: hp--, tint white flash briefly then clear, particle burst, score if dead. Small knockback: set position offset.
- Damage feedback: hit spark at bullet impact + alien flash; alien death: explosion particles + score popup text.

Player damage:
- overlap player/alien: if now > invulnUntil → health -= 12, invulnUntil = now + 700, camera shake, red flash overlay, alien bounce away (move alien back 30px and set stun), also tween player alpha blink.
- If health <= 0 → game over.

Wave clear: aliens.countActive() === 0 and not spawning → after 800ms start next wave, wave++, banner. Need to avoid triggering at start before spawn: set spawn immediately at startWave.

Wave composition: count = 4 + wave*2, speed multiplier = 1 + (wave-1)*0.14. Spawn all at once? Spawn staggered using time events perhaps; simpler spawn all at once with spawn delay via tweens? Just spawn all at once at start; small delay between spawns looks better: use this.time.addEvent with repeat count-1 delay 120.

Also add difficulty: enemies get hp 1 + Math.floor((wave-1)/3).

Cap alien count? fine.

Wave clear check in update: if waveActive && pendingSpawns===0 && aliens.countActive(true)===0 → waveActive=false; show banner; time.delayedCall(1200, startWave next).

Game over: state = 'over'; physics.pause(); player invisible? Show explosion. Overlay container with texts. Restart button: interactive, on pointerup → restart: reset all data, destroy all aliens/bullets, physics.resume(), player pos center, health 100, score 0, wave 1, hide overlay. Need careful update of HUD.

Overlay container built once in create, hidden. Restart button via zone/rectangle.

Also make restart button keyboard R? optional.

HUD health bar: graphics redrawn; healthBarBg and fill. Also numeric health text "HP 100".

Screen flash on damage: graphics overlay full-screen red alpha, tween alpha to 0.

I'll write the file now.

Details on `this.input.activePointer.leftButtonDown()`.

For camera shake use this.cameras.main.shake(120, 0.006).

Particles: use Phaser particles with generated 'spark' texture, emitter explode. In 3.80, this.add.particles(x, y, texture, config) returns emitter. For one-shot: this.add.particles(x,y,'spark',{speed:{min:60,max:220}, lifespan:350, quantity:8, scale:{start:1,end:0}, emitting:false}).explode(10). Simpler helper function burst(x,y,color,tint). Particle texture white and tint per emitter via config tint.

Collision handling with physics bodies using group overlap: this.physics.add.overlap(this.bullets, this.aliens, this.onHit, null, this). Note group overlap with two groups works.

Bullets group: this.physics.add.group({classType: Phaser.Physics.Arcade.Image, maxSize: 60, runChildUpdate: false})? Use group.get then set texture. Simpler create Image, add to group.

Use `this.bullets = this.physics.add.group();` then `const b = this.bullets.get(x,y,'bullet')` — get creates with texture if key provided? group.get(x,y,key) creates a Sprite via createCallback with classType default Sprite. Yes physics group get(x,y,texture) creates Sprite and enables body. Then setActive/visible true, body.reset.

Aliens group similarly `this.physics.add.group()`.

Player: this.physics.add.image or sprite; use this.add.image + physics.add.existing, body circle.

Bodies: player body circle radius 18, offset. alien circle radius ~14. bullet small.

World bounds: arena 960x640 canvas. Physics world bounds set to (0,0,960,640) with checkCollision. Player collideWorldBounds true. Hud occupies top 60 px but fine—aliens and player can move under HUD? Top bar semi-transparent, gameplay area full. Maybe restrict world bounds top to 64 and player cannot go under HUD. Set physics world bounds (0,64,960,576) then background border drawn accordingly. Use PLAY_TOP=64.

Canvas dims: 960x640.

Pointer world coords: use pointer.worldX (works with camera; no camera scroll, but FIT scaling handled by Phaser).

Clicking on Restart button also fires? state over so no.

Also prevent context menu? left click only.

Text font: use system fonts 'Arial'. Use Phaser text with fontFamily monospace maybe "Courier New". Fine, no external.

Starfield: generate random dots in graphics.

Let me write.

Wave banner: text center with tween scale/fade.

Score popup: small text at alien location float up fade.

Now HUD layout:
- Top bar bg rect height 64 color 0x0a0f1e alpha 0.9, bottom border line.
- HP label at x=24,y=22 font 14 bold 'HEALTH', bar rect at x=24,y=38 width 180 h 12 with border; fill green→red based pct.
- Score: right side text right-aligned x=936 'SCORE 0000' with label? simpler combined: `SCORE 0` at x=936 y=20 right aligned; `WAVE 1` at x=936 y=42.
- Center title "ALIEN SIEGE" small at center? maybe not needed, put "NEBULA SIEGE" center top. Keep simple.
- Controls bottom-left: `WASD move · Mouse aim · Click / hold to fire` at bottom, semi transparent panel.

HUD drawn in scene because camera shake moves HUD? Camera shake moves everything, including HUD; could use a second camera for HUD, or setScrollFactor(0). Shake would still shake scrollFactor-0? Camera shake affects all rendered by camera; to avoid, use separate UI camera. Simpler: skip camera shake on HUD by using a second camera for UI. Alternative: no camera shake, use screen flash and particles only. To keep it simple and robust, implement shake only slightly? I'd rather use a separate UI scene? That adds complexity. Alternative: camera shake but HUD elements are scrollFactor 0 — they shake too. Let's just avoid shake, use flash. Actually visible feedback required for projectile hit — particles + alien flash + score popup are enough. I'll do tiny shake maybe on player damage only... skip entirely. Fine.

Let's write code.

One more: "aliens advance toward the player" — homing velocity each frame.

Alien visual: rotating slightly? maybe rotate toward player too. Sprite shape roughly symmetric; add rotation toward movement + jelly scale tween pulsing. Use per-alien tween scale 0.95→1.05 yoyo repeat -1 with delay random.

Player invuln blink tween on alpha.

Damage to player also when bullet hits? no.

Let's write index.html.

Add keyboard 'R' restart when game over. Also Enter.

Details for restart: this.scene.restart() would reset everything automatically and is simplest. Requirement: restart restores health, score, first wave. scene.restart() does that cleanly. Use that. But then game-over overlay from old scene destroyed automatically. Great — restart button calls this.scene.restart().

Careful: this.scene.restart() during pointer callback is fine.

Wave logic in scene restart resets too.

Player death: explode player, hide; input disabled.

Let's code.

```js
const GAME_W = 960, GAME_H = 640, TOP = 64;

class BootScene extends Phaser.Scene { preload? } 
```
Just one Scene class MainScene with create generating textures via Graphics.

Textures generation:

```js
makePlayerTexture() {
  const g = this.make.graphics({add:false});
  // ship pointing right, 48x36
  g.fillStyle(0x0b3a4a, 1); ... 
}
```
Use generateTexture('player', 48, 36); destroy graphics.

Ship: cyan body triangle with darker outline and glow.

```js
g.lineStyle(2, 0x9ffcff, 1);
g.fillStyle(0x25c9e8, 1);
g.beginPath(); g.moveTo(46,18); g.lineTo(6,3); g.lineTo(14,18); g.lineTo(6,33); g.closePath(); g.fillPath(); g.strokePath();
g.fillStyle(0xd8feff); g.fillCircle(24,18,4);
g.fillStyle(0x7ef7ff,0.9); g.fillTriangle(10,10,20,16,12,18)? 
```
Keep simple.

Alien: 36x36, body ellipse with legs:
```js
g.fillStyle(0xc94fff);
g.fillEllipse? Graphics has fillEllipse? Yes fillEllipse(x,y,w,h).
```
Graphics API: fillEllipse(x, y, width, height). Yes exists. fillCircle too, fillTriangle.

Alien design: purple ellipse body 26x26 centered 18,18; 3 eyes small lime; spikes around: fillTriangle at 4 directions.

Bullet: 14x6 rounded rect with bright core:
```js
g.fillStyle(0xffd75e, 0.9); g.fillRoundedRect(0,1,14,4,2); g.fillStyle(0xffffff); g.fillRoundedRect(2,2,8,2,1);
```
Rounded rect radius 2 fine.

spark: 6x6 circle white with alpha? generateTexture with fillCircle(3,3,3) color white; tint in emitter.

Also 'ring' texture for wave? skip.

Reticle drawn every frame via graphics at pointer world pos: circle + cross lines, color lime. Set depth high.

Now writing physics bodies.

Player:
```js
this.player = this.physics.add.image(GAME_W/2, GAME_H/2+80, 'player');
this.player.setDepth(5);
this.player.body.setCircle(16, 8, 2)? 
```
The image is 48x36; body circle radius 16 offset (48/2-16=8, 18-16=2). Good.
this.player.setCollideWorldBounds(true);
this.player.setDrag(900)? Instead set velocity directly. Use acceleration? Direct velocity with smoothing: velocity = lerp toward target. Simple direct velocity fine.

Bullets:
```js
fire() {
  const b = this.bullets.get(this.player.x + Math.cos(rot)*26, this.player.y + Math.sin(rot)*26, 'bullet');
  if(!b) return;
  b.setActive(true).setVisible(true).setDepth(4);
  b.setRotation(rot);
  b.body.reset(px,py) ... 
  b.body.setCircle(3) ...
  b.setVelocity(cos*760, sin*760);
  b.life = 1400;
}
```
Careful with `b.body.reset(x,y)` then setVelocity after. Use `b.enableBody(true, x, y, true, true)`? For group.get objects that are inactive. In Phaser 3, physics group.get returns an active sprite created by group; when destroyed they're removed. Simpler: create bullets with group.create each shot and destroy on hit, with cooldown capping counts. Fine for this scale — no pooling complexity:

```js
const b = this.bullets.create(x, y, 'bullet');
b.setRotation(rot); b.setDepth(4);
b.body.setAllowGravity(false);
b.setVelocity(...);
b.setData('born', time.now)
this.time.delayedCall(1400, ()=>{ if(b.active) b.destroy(); });
```
Group create enables body automatically. Bullet body small circle radius 3 with offset. Also add trail? skip.

Muzzle flash: small particle burst at spawn (2 particles). Might be heavy with 150ms fire; ok quantity 2.

Hit handling:
```js
onBulletHit(bullet, alien) {
  bullet.destroy();
  const hp = alien.getData('hp') - 1;
  this.burst(hitx, hity, 0xffe066, 5);
  alien.setData('hp', hp);
  alien.setTintFill(0xffffff); // flash
  this.time.delayedCall(60, ()=> alien.active && alien.clearTint());
  // knockback
  const ang = Math.atan2(alien.y - this.player.y, alien.x - this.player.x);
  alien.x += Math.cos(ang)* -? 
```
Actually knockback away from bullet direction: push alien in bullet direction:
```js
const a = bullet.body.velocity? destroyed already. capture before destroy.
```
Compute from bullet rotation: push alien by 8px along rotation. Use alien.setPosition(alien.x+Math.cos(rot)*10, ...). Then after 60ms aliens homing resumes.

On death: score += 10*(1+wave?) just 10. Maybe 10 + wave. Keep 10 flat. Bigger aliens? give score 10.

death: burst particles 12, scorePopup, destroy alien. Also flash camera slightly? Use this.cameras.main.flash(60, 80, 200, 255)? could be distracting. Skip camera flash on hits; use flash on player damage.

Player damage handling with overlap:
```js
this.physics.add.overlap(this.player, this.aliens, this.onPlayerHit, null, this);
```
Overlap fires every frame while overlapping; invulnerability window handles.

onPlayerHit(player, alien) { if(!playing) return; if(time.now < invulnUntil) return; ... }

Damage: 10 + wave*2? Keep 12 constant-ish: damage = 10. health 100 → 10 hits. Maybe 15 for challenge → ~7 hits.

Push alien away: set alien position away by 40 px and give it a "stun" until time; since homing resets velocity each frame, set alien.setData('stun', now+350) and in update skip homing if stunned and let velocity continue away. Do:

```js
const ang = Math.atan2(alien.y-player.y, alien.x-player.x);
alien.setData('stun', time.now + 320);
alien.setVelocity(Math.cos(ang)*320, Math.sin(ang)*320);
```
In alien update: if stun active, decay velocity maybe; when stun ends, homing resumes.

Also on damage, health bar update, red vignette flash, and player blink:
```js
this.tweens.add({targets:this.player, alpha:{from:0.25,to:1}, duration:110, yoyo:true, repeat:4, onComplete: ()=> this.player.alpha=1});
```
Careful with delayed restart.

Game over view: container with dark rect covering play area, "GAME OVER" text, "FINAL SCORE X", "WAVE REACHED N", restart button rect + text interactive with hover color, plus hint "or press R".

Button: create Rectangle gameobject interactive; on pointerdown → this.scene.restart(). Also add pointerover/out fill color.

Wave banner: create per wave text center, tween alpha 0→1 then 1→0, and scale. Use this.tweens.add.

Also wave start: announce "WAVE N — INCOMING". Show at top center below HUD.

Controls text bottom-left with small panel.

Also add crosshair reticle.

Check wave clear loop: use update check with waveActive flag and spawnRemaining counter. spawnRemaining decremented in spawn callback. When all spawned and aliens.length===0 → clear.

Initial start: startWave(1) at create with slight delay 300ms so player orients. Actually wave 1 immediately then banner.

Spawn positions: random edge inside margin 40 from play bounds: choose top/bottom/left/right, ensure distance from player > 240. Loop attempts.

Arena border: graphics line rect, plus vignette. Draw grid subtle.

Add stars twinkle: static stars + a few drifting? Static fine.

Also clamp aliens in bounds: set collideWorldBounds true, bounce 1 with homing causing sticking; instead in update if out of bounds, clamp positions. Use collideWorldBounds false and in update clamp within play rect. Good.

Alien update loop: aliens.children.each? use this.aliens.getChildren().forEach.

Performance fine.

Let's write the code now, carefully.

Wave scaling: count = 5 + (wave-1)*2 (wave 1:5, wave2:7...), speed = 62 + (wave-1)*9, hp = 1 + Math.floor((wave-1)/3), spawn interval 130ms.

Also cap children? fine.

Bullet alien collision body sizes: alien body circle radius 15 using setCircle(15, 3,3) on 36x36 texture.

Let me code and test.

HUD text values updated via functions updateHud().

Health bar graphics: this.healthBar = this.add.container? Just a Graphics object redrawn: clear, fill bg, fill pct.

Fonts: use fontFamily: '"Trebuchet MS", Arial, sans-serif' or monospace. Use 'monospace' style with letterSpacing? Phaser text supports letterSpacing maybe not in 3.80? Text has setLetterSpacing in 3.60+. Use it cautiously. Skip.

Write now.

Also background non-network: body background radial gradient CSS.

Scale config:
```js
const config = {
  type: Phaser.AUTO,
  parent: 'game',
  width: GAME_W, height: GAME_H,
  backgroundColor: '#05070f',
  physics: {default:'arcade', arcade:{gravity:{x:0,y:0}, debug:false}},
  scale: { mode: Phaser.Scale.FIT, autoCenter: Phaser.Scale.CENTER_BOTH },
  scene: [MainScene]
};
```
window resize handled by FIT.

Reticle: this.add.graphics().setDepth(900); update to pointer.

Let's produce the file.

I must ensure `this.bullets.create` body not null etc.

For pointer fire: check `this.input.activePointer.isDown && this.input.activePointer.leftButtonDown()`. On touch, isDown true but leftButtonDown false → touch play impossible; okay. Add space also fires for accessibility? Controls only mention left click. I'll allow Space as alternate (display?). Keep hidden but supported.

Now game over: set this.state='over'; this.physics.pause(); this.player.setVisible(false); burst player. But physics.pause stops tweens? Tweens unaffected. Show overlay after 300ms delay.

Since physics paused, aliens freeze. Good.

Also stop firing on over.

Restart via scene.restart(): physics paused state persists? Scene restart recreates physics world (world resets paused false I believe — scene systems shutdown and physics world is recreated on start? Arcade world is destroyed and recreated on scene start, paused false). To be safe call this.physics.resume() at create start.

Wave clear detection runs only when state playing.

Score popup text creation: this.add.text(x,y,'+10',{...}).setDepth(50); tween y-=26 alpha 0 duration 600 onComplete destroy.

Sound: no audio assets; could generate WebAudio but not needed. Maybe simple synth beep for shooting/hits via AudioContext? Adds complexity; not required. Skip (could have muted complexity). "Do not use external image or audio assets" - fine.

Let's write.

One concern: generating textures in create each restart — keys already exist; use if (!this.textures.exists('player')) guard.

Let me write the file now.

Now test in browser. Note: controlsPanel uses children.list indexing hacky but harmless. Let's run.

Initial view looks good but no aliens visible after ~0ms (they spawn up to 150*4=600ms). Need screenshot after some time. Also health bar looks fine. Let me wait and screenshot, then test movement/firing via mouse actions.

Screenshot again after a delay via a dummy bash sleep.

Only 2 aliens visible, but wave should spawn 5. Some may be off-screen? Wait, aliens should all be in play area. Only 2 shown at 2s. Hmm, maybe spawn point overlaps? Actually the screenshot appears zoomed/cropped relative to canvas? The image is 1200x800 viewport and shows the canvas nearly full width. The game canvas FIT scaling—image shows canvas 1200x800? Actual canvas is probably ~1180x787. Some aliens may be hidden by spawn pop? no.

Wait there's a weird white circle at right edge (x ~1143,y~524) — that could be an alien sprite rendered as white ball, maybe an alien with tint? It looks like a white circle without spikes; that could be the reticle? No, reticle is drawn at pointer, which might be at that position. Yes, the reticle near right edge! But reticle drawn at pointer coords (initial pointer at 0,0?) It's a circle at ~right edge — maybe pointer near there.

So only 2 aliens. The other 3 may not be spawned due to `this.aliens.create` returning null? Or because spawn positions are within play area but the screenshot... hmm. Let me inspect scene state via browser inspect (console). Browser tool inspect gives DOM info maybe not JS. Use bash? Can't access page JS directly. I can use browser inspect, which likely returns DOM/console. Let me add a temporary debug via browser? I can evaluate JS only through tools? No evaluate tool. I can use the browser type? Not JS execution.

Alternative: check by adding console.log temporarily (then reload) to see counts. Actually could be that aliens spawned under HUD? Spawn top side y = TOP+margin=110, visible. Canvas visible area starts below HUD; fine.

Wait maybe the other aliens are near player and overlapped/behind? No.

Possibly aliens collide with each other? Not set. Group physics config default collideWorldBounds false.

Look again: top-right alien at (1036,145) with a small particle burst near it. Bottom center alien at (894,721). White circle at right (1143,524). Could that white circle be an alien with white tint? No tint applied except flash from bullet. Hmm, it could actually be a bullet fired? no clicks yet. The reticle at pointer, pointer default position (0,0) or center? Reticle has crosshair lines; the shape shown is just a circle with white fill maybe. Hard to tell.

Hmm — actually maybe the screenshot is cropped: screenshot viewport 1200x800; canvas rendered at 1200x800 (FIT with aspect 1.5; 1200/800=1.5 matches). So full canvas visible.

Wait, the "white circle" might be the mouse cursor indicator rendered by the tool? The reticle should be green-ish. It's white filled circle, radius ~6 px. Hmm.

Possibility: aliens spawn but some destroyed? No.

Let me count: maybe spawn happened at 220ms + i*150; first at 220, 370, 520, 670, 820, then wave? At 2s all 5 should be present. Unless aliens spawned outside bounds and got clamped... still visible.

Could the top-right "alien" and bottom one be scale ~1, and the others are behind nebula? no, depth.

Let me reload and screenshot with shorter wait; or inspect the DOM to see canvas size. Let me try adding console logging temporarily by editing the file to include a debug interval logging aliens count, then reload and read console.

Actually easier: use the browser `inspect` action to see if it gives JS state. Let's try.

Now 5 aliens visible at various positions. Good — earlier screenshot may have caught before spawns. The white circle earlier was probably the reticle drawn at pointer.

Wait, aliens seem not to have moved much? In 2s from previous they should approach. First screenshot at 2s had alien at (1036,145), now at (1014,163) - moved toward center slightly. And new ones appeared. Fine. The white circle is reticle indeed (it was drawn as circle only? cross lines maybe faint). Hmm reticle at (1143,524) with just circle - maybe pointer is at edge and cross lines off? No, lines from rx-18 to rx-6 etc. would show. Maybe the white circle is the mouse pointer drawn by browser? Not in screenshot usually. Whatever.

Now test movement via key press and firing. Browser key action: I need press W: action "key" with text "w"? Let me check the tool behavior—`key` takes text. I'll hold key? Each action is a single key event perhaps keydown only. Let's try key with text "d" and screenshot. Then move mouse and click to fire, screenshot.

Important: firing via hold requires pointer isDown; a click is momentary, firing a couple bullets. Use click at position aiming at an alien and check score/bullets.

Player rotated toward pointer at (860,385) — yes facing up-right. But no bullets visible; they'd despawn in 1.5s, click may fire one and it's already gone after screenshot delay. Score is 0 still since it may have missed the alien at (1070,264). Also reticle correctly on pointer.

Aliens at corners still far — are they advancing? Between screenshots, positions changed slightly: alien top-left from (66,203) to (88,212); top-right (1014,163) to (998,175); bottom-left (216,726) to (239,716); bottom-right (859,696) to (844,688); right (1101,521) to (1078,518). They are moving toward player (center ~600,480) but slowly (speed ~62-78). Fine.

Wait aliens started at margin 46: top-left at (88,212) not near top edge at y=110. Hmm they should spawn at y=TOP+46=110. They moved. okay.

Now test hold-fire. The browser click is a quick press; to test sustained fire need mouse down duration — tool doesn't support press-hold except drag. Use drag from player toward alien which holds? drag may fire during motion. Let's do drag from (700,450) to (1000,400) — pointer down at start and up at end, firing over duration. Better to test hitting alien. Player ship at ~600,480. Alien at 998,175. Drag from (600,480) to (990,185): bullets fire along direction to pointer during drag, may hit alien. But pointer aim changes while dragging, bullets spray. Might kill something.

Alternatively test firing at a nearby alien by dragging. Let's aim at the alien at (1078,518) moving toward player; drag from near it to it. Let's try drag from (700,450) to (950,450)? Bullet path from player along aim; alien at ~1078,518, not aligned.

Better: shoot at alien top-right at (998,175): line from player (600,480) direction (398,-305). Aim at pointer (1000,175) and hold. Drag from pointer position (1000,175) to (1000,175)? Zero-distance drag maybe not registers. Drag from (900,300) to (1000,175) would sweep aim; bullets fired at early aim would go up-right, alien may be roughly in path. Hmm.

Maybe easier to verify score via clicking repeatedly at alien position as it advances: click on alien location several times. Each click fires one bullet along that direction; the alien moves though. Let's click a few times on the top-right alien trajectory.

Actually a better approach: temporarily use drag to hold pointer down and keep aim fixed by dragging zero? The drag action with same start and end may still press-hold-release over some frames. Let's try drag from (998,175) to (998,175) and immediately screenshot. Or use "key" for space to fire continuously? The key action may hold? likely keypress only.

Let me just try dragging.

Excellent: firing works, bullets stream toward pointer, score 10 (killed one alien). Wave 1 aliens remaining 4 visible. Note: bullets travel along the aimed path toward top-right; one alien was killed.

Interesting: the reticle is at (1005,185) which visually matches. Good.

Now test movement: press 'd' key. And test damage/game over eventually. Wave clear might take a while manually. We can verify wave advance by killing all 4 remaining. Let's aim at each and click. Current aliens roughly (in canvas coords scaled 1:1 with viewport? canvas is 1200 wide; game 960 → scale 1.25. Screenshot coords are viewport coords, click coords also viewport. So aim via screenshot positions directly).

Aliens: (220,290), (917,508), (710,586), (392,620). Player (550,510).

Let me click at each a few times quickly. Killing needs one bullet hit (hp 1). Alien at (917,508) near; click there quickly. Bullets travel 780 px/s; distance ~450 → 0.6s. Alien moves ~40px. So aim slightly ahead — homing means they move toward player, so clicking directly on current position is close enough given 40px radius body? click at alien position leads bullet to arrive at position alien moved from... but alien moves toward player along that same line roughly, so bullet path coincides with alien path. Good.

Let's do a few clicks at the alien coords, waiting between. Use drag small as hold for 1-2 shots. I'll drag at each alien location briefly.

First test movement with key 'd' to verify.

Player got hit (-15 HP) and red damage flash, aliens close. The 'w' key press didn't seem to move player much (single keypress likely keydown+keyup quickly, movement tiny). Player at (550,490) vs before (550,510) — moved up ~25px? yes maybe held briefly.

HUD updated 85/100. Damage feedback works. Need to verify movement more clearly: press key and screenshot quickly? Each tool call waits ~? Movement per key event may be only one frame. Let's do key 'a' and compare ship x over screenshot. Alternatively use drag not relevant.

I want to verify game over + restart. Easiest: let aliens hit player repeatedly — they are adjacent, invuln 720ms, so ~10 hits over 7s. Wait a few seconds and screenshot.

Also I need to verify wave clear → next wave. Could be done by killing all aliens, but risk dying first. Health 85, 4 aliens nearby. Fire while aliens near: they're overlapping player; shooting them requires aiming away and bullet spawns outside? If alien adjacent, bullet may spawn past it and miss. Could die.

Maybe let game over happen (verify), then restart (fresh health/score/wave 1), then test wave clear by killing 5 aliens deliberately. On restart, the wave 1 aliens spawn away from the player so I can pick them off.

Let's wait ~8s for death.

Game over works with overlay and Restart. Click Restart and verify HUD resets.

Restart restored health 100, score 0, wave 1. There's a stray white circle at left edge (~57,567) again — this is likely the mouse cursor indicator? It appeared in all screenshots at left. Hmm, could be the reticle at pointer stuck at old position? Actually reticle should be at (600,563)? No, the reticle visible at (600,563) with crosshair. The white filled circle at left is unexplained. Could it be a Phaser mouse pointer? Phaser doesn't render cursor.

Wait — is it an alien spawn? No, aliens purple. Could it be a "spark" particle left over? Particles decay. A white circle diameter ~14 px at viewport → 11 game px. Particle spark is 8px texture scale 1 → 10px at 1.25. Could be a leftover particle from player death that persists? Particles have lifespan 420ms. Hmm, in this new scene? Particles from the previous scene destroyed.

Look at first screenshot: also white circle at right edge (1143,524) when reticle at (1005,185). So there's always exactly one white circle away from the reticle. Possibly it's the browser's actual mouse cursor rendered in screenshot? Cursor would not move based on... In the first screenshot the pointer was around (1143,524)? Actually maybe the tool's click at (860,385) moved pointer; screenshot reticle was at ~(860,385)? In that screenshot reticle appeared at right around (1030,320)? Hard to recall.

Maybe the white circle is the OS-level cursor, and the reticle is a separate rendering. The browser tool screenshots may include cursor. In the game-over screenshot there were two small purple circles at ~(410,410) and (690,500) — those are aliens frozen behind overlay. The white circle could well be the pointer cursor drawn by the headless browser. It's outside the click position though... but in the last screenshot, cursor may be at previous drag position? I clicked Restart at (600,563) so cursor there, yet white circle at left.

Hmm. Could be a Phaser particle emitter that leaked. If particles from `burst` linger due to `emitter.explode(count)` + delayedCall destroy - destroyed after 600ms. Not likely after seconds.

What about the reticle graphics? It's cleared each frame and only drawn when playing. The white circle is filled white—reticle fill circle radius 1.6 at center, green. Not this.

Another candidate: star? Stars are 1-2px. No.

Maybe it's a Phaser default mouse pointer from the runner? I recall browser tool renders cursor as a circle? Possibly the harness injects a cursor dot. In the very first screenshot (before any mouse action) the white circle was at the right edge. Pointer default position would be (0,0) though, and reticle drawn at (0,0)... but reticle appeared at circle? In screenshot 1, only one circle at right edge and no crosshair visible; that suggests the white circle IS the browser cursor at default pointer position, and the reticle crosshair might have been off-viewport or overlapping? Hmm reticle would be a green crosshair around it. In screenshot 1 (2s), there's no crosshair anywhere visible. So reticle was at the white circle? The white circle at right edge looks pure white filled, while reticle is green ring + cross. Unless rendering resolution low, it looked like circle.

In the second screenshot, reticle visibly at (1005,185) plus white circle at (1143,524). So two things. The white circle at 1143,524 might be the cursor location from before tool click? The click set cursor at (860,385) though. Hmm no.

Wait, in the screenshot after clicking restart: reticle at (600,563) matches latest click at Restart (cursor there). White dot at (57,567) doesn't correspond. So likely the white dot is something in-game: maybe an alien that died and left a "spark" emitter still alive? Or... could be the player's engine glow? No.

Hmm, could it be a bullet? Bullets are yellow rounded rect. A white circle could be a bullet spawned when click on restart? On click restart, pointer down might fire a bullet immediately in new scene at pointer direction... White-ish? bullet texture is 18x9 rounded rect with white core; at small scale looks like white oval. The dot at left is round white, roughly 10x10 viewport = 8x8 game. Bullet has yellow; would look yellowish at 1.25 scale with white center. In game over screen before restart, already a white dot existed at left edge, so not from restart.

Could it be a star with large size? Stars max radius 2 → 5px viewport. White dot is ~12px. No.

Maybe leftover particles from the player death explosion in old scene, rendered by a particle emitter whose destroy failed? Death burst at player position (600,490), not left edge.

Actually, maybe it is the ring "hit" white flash? no.

Whatever—it's cosmetic, small, and likely the harness cursor. Not worth chasing. But let me verify by taking a screenshot without mouse interactions after moving pointer elsewhere... Actually the browser tool's click at (600,563) is over the canvas so cursor is there. Left dot persists.

Hypothesis: a Phaser Image "bullet" got created when pointer down on restart happened during scene restart? Not in old scene. Hmm.

Let me use browser screenshot after waiting 3s more to see if dot persists. If it does, check its role: possibly enemy that spawned with texture 'spark'? No, aliens use 'alien'.

Could it be the 'player' image for the old scene not destroyed? Old player was hidden.

One more candidate: the damageFlash graphics covers play area but not white.

I'll test in a fresh reload: on fresh load, is there a white dot? In the first screenshot, yes at right edge. In initial screenshot at frame 1, no dot visible (but no aliens either). Hmm, in the very first screenshot the right edge had a partial white circle at (1143,524)? That was screenshot 2 (2s).

Fresh reload and immediate screenshot with pointer nowhere should show dot at same spot if it's in-game. Let me reload and take two screenshots 1s apart to see if the dot moves/vanishes. Also test wave clear by killing aliens.

Actually a likely explanation: leftover particle from burst at spawn position with `emitting:false` and explode; particle lifespan max 420, but `emitter.destroy()` delayed 600ms. Fine.

Whatever, let's reload and observe.

Actually! I think I know: `this.burst(b.x, b.y, 0xfff0a0, 2, 90)` muzzle flash, and killed aliens. A particle with lifespan 420 can't last seconds.

Could the white dot be an alien with hp flash `setTintFill(0xffffff)`? TintFill fills whole sprite white, but the alien would then be a white silhouette/ellipse, not circle. A hit alien with tintFill for 70ms — screenshot might catch it. In the game-over screenshot, there's a small purple half-transparent alien at (690,500), plus white dot at left. Hmm.

Let me reload and check.

Fresh reload: no white dot, no aliens yet (initial screenshot before spawn delay). So white dot was likely a mouse cursor artifact or particle. Ignore.

Wait, alien spawns don't appear here at frame 1 — expected, they spawn 220ms after. Good.

Now test wave clearing → wave 2. I'll kill aliens one by one; but they are far initially. Use drag at each alien to hold fire. Let me wait 1.5s for spawns, screenshot, then attack.

Actually to verify wave progression efficiently, I could aim and hold at each alien. Alien HP=1, so a single hit kills. Bullet travel time up to 1s. Aliens move toward player, so shots along the line hit.

Let me wait for spawns and screenshot.

Hmm, only 2 aliens visible at 1.5s (should have 5 by then: spawn starts 220ms, 5 spawns at 150ms apart → last at 820ms). So where are the other 3? Unless they are near player hidden? No. Are aliens being spawned but instantly destroyed due to world bounds? collideWorldBounds false. Hmm.

Ah wait — maybe the screenshot happens before the full 1.5s? bash sleep 1.5 then screenshot call latency; should be enough. But the first screenshot in the previous session at 2s also had only 2 aliens, and next screenshot showed 5. Also in this session, the reload screenshot at frame1 had no aliens and then this showed 2. So aliens spawning is much slower than expected? Spawns at 220+150i. At 1.5s after reload, all 5 should exist. Unless the browser tool pauses the page rendering loop between calls? The page may be throttled/paused while no tool attached? Likely the headless browser only advances when screenshots/actions occur. So the visible state lags — time may advance in real time though with requestAnimationFrame throttled when not captured. That explains slow spawns.

So can't reliably time-based verify. Fine — mechanics verified already.

Wave 1 has 5. To test wave clear, I need to kill all 5. I can fire at these two visible then wait for others to appear and kill them. Might be time-consuming but doable. Let's shoot the left alien at (80,523) with drag at its position; bullet from player (600,480) to (80,523) distance 520, travel 0.67s. Hold fire longer.

Use drag from (80,523) to (85,525) — the drag press duration maybe ~100ms → 1 bullet. Fine, hp1.

Then wait, screenshot.

Killed the left alien: score 10, burst particles at its location. 4 aliens remain (top-right cluster). But notice bullets streaming left continuously — the drag left the pointer down? It appears bullets keep firing after the drag, because the drag ended at (84,525) but pointer still down? The burst in front of ship suggests firing continues. Possibly the drag ended, but the screenshot captured residual bullets in flight (many along path). Each bullet is a yellow dashed line? No—the bullet texture at scale is a short capsule; the line appears dashed continuous — many bullets fired over time while pointer was held during drag, spaced closely. That's expected.

Now kill remaining 4. Aim at each. They're on right side around (857,197), (1098,244), (1061,368), (1082,478). The player is at (645,465) in viewport. Wait, player moved? It's at (645,465), previously (600,470). Recoil minuscule, probably viewport coords differ slightly. Anyway.

Kill with drags at each position. Since hold-fire streams, one drag per alien may overkill multiple. Let's do drag near (860,197) etc. But careful not to waste time. Wave 1 4 aliens left; after all dead, wave 2 begins with 7 aliens and faster.

Let me drag along the right cluster sequentially with a single continuous drag maybe from top (860,197) to (1090,480) which sweeps aim and sprays. Aliens may be hit. Let's do a drag from (860,197) to (1090,480) with intermediate aim — durations unknown, may fire several bullets across path. Try.

Score 75 = 10x5 kills + wave clear bonus 25? Wait 5 kills = 50 + bonus 25 = 75. Wave still shows WAVE 1 — the next wave call is delayed 1300ms. Aliens all gone. Wait for wave 2.

Also confirm wave-2 starts and shows 7 aliens faster. Sleep then screenshot.

Wave 2 started with 7 aliens (count 5+2=7? I see ~7-8), speed increased. HUD shows WAVE 2, hull 70 (aliens hit during inter-wave? Actually a "-15 HP" popup shows damage). Health bar updates. Good.

Wave 2 aliens are already near the player and dealing damage. That's because my drags left the pointer held? No—aliens advanced during the wait. The player has 70 HP.

One issue: aliens spawn and immediately close in fast; fine.

Also note hull display and popup working.

Remaining checks:
1. Movement via WASD clearly. Let me hold a key with repeated key events? The key action sends one event; the movement in earlier test was small. I could verify by pressing 'a' and screenshot immediately. Ship at (588,492) viewport. Press d and screenshot; expect x increase slightly (one frame 265*0.016≈4px → 5px viewport). Hard to see. But movement mechanics are straightforward and the physics body is set; initial test showed y change from 510 to 490 after 'w' (though that could be no change—actually player moved up). Hmm, in the first session player at (550,510) then after 'w' at (550,490) = 20px move, so keys work while held ~80ms.

2. Game over + restart verified.

3. Aim/fire verified.

4. Damage verified.

One visual concern: bullet trail looked like a continuous line of bullets while holding — normal.

Another: the reticle seems small but visible.

Let me also check that clicking on the game over overlay's Restart works after a restart (verified once).

Potential issue: scene.restart while overlay is visible; new create resets. Verified.

One bug risk: `this.controlsPanel` references weird children list entry; harmless.

Another: the top HUD bar shows the health bar and text but hp text at x=240 right-aligned overlapping? Looked fine.

Also wave 2 aliens at 70 HP after just starting—player likely got hit during wave 1 clear? Actually after the screenshot with 100 HP and no aliens, then wave 2 spawned; screenshot shows -15 HP popup. Fine.

Now check whether game over can be triggered reliably. Already done.

Consider `this.player.setDamping(true); setDrag(0.0001)` with direct setVelocity calls — no functional issue since velocity is set each frame.

Check that when the pointer leaves the canvas the aim still works / reticle maybe frozen at edge. Fine.

Edge case: firing while game over → update returns before firing. Good.

A real issue: In `onPlayerHit`, when hp<=0, `this.player.setTint` delayed calls etc. fine.

Another: wave clear check could trigger between restart frames? state resets waveActive false. Fine.

Also `this.physics.pause()` and scene restart: at create we call this.physics.resume() — good.

Check the game-over screen restart button is clickable: verified.

Potential issue: On restart, `this.overlay` etc. recreated; old timers destroyed with scene. fine.

Let me test movement more concretely using browser key press with a longer hold maybe the tool supports keydown only. Check tool description: action "key" with text. Probably sends a keypress. I saw movement happened. Good enough.

Also test aim rotation toward mouse: ship visibly rotates to point at the reticle — yes in screenshots ship points right-down toward reticle at right edge.

One improvement: aliens pile up and overlap; okay.

Something to double check — score after wave clear showed 75 with 5 kills: 50 + 25 bonus. Good.

Also ensure the first wave actually contains 5 aliens and not more; yes.

Let me test death and restart once more quickly with current state (70 HP, 7 aliens close). Wait ~4s and screenshot → game over, click restart. Actually already verified both. But let me verify the restart button with a fresh state after game over with wave > 1, ensuring wave resets to 1 and score 0. Previously restart reset to wave 1/score 0/100 HP. Good.

Now check an edge: after game over if you click on the Restart button, physics paused → bullet creation? No firing.

One more concern: in the game-over overlay the "Restart" button at GAME_H/2+132 = 452 → viewport y = 452*1.25 ≈ 565. I clicked 563 successfully.

I think the game is functionally complete. Let me improve a couple of small things:
- The `controlsPanel` unused array hack remove.
- Add a small "wave enemies remaining" indicator? Not required.
- The damage flash covers arena and red — verified.
- Ensure pointer firing while clicking outside canvas doesn't get stuck? Phaser handles pointerup outside canvas? Occasionally yes, but window pointerup usually. Fine.

Maybe add sound via WebAudio? Not required; skip to save time.

One thing: "Display controls on screen" – done bottom-left.

"aliens advance toward player" verified.

"Projectile hit produces visible feedback" — particles + flash + score popup; verified via particle burst and score.

I should verify the hit flash/particles in a controlled way: the last screenshot showed no burst since screenshot later. Earlier after the first drag I saw particles at impact point and score change. Good.

Potential quality issue: enemy hp scaling hp=1+floor((wave-1)/3) means wave 1-3 one-shot. Fine.

Also initial wave banner likely displays, didn't capture but code straightforward. Let me confirm by reloading and screenshotting right away (~0.5s) to catch "WAVE 1" banner. Reload resets though; fine since final artifact fresh. Let me reload and screenshot at frame capture to verify banner. Also confirms initial state.

Use browser reload then screenshot immediately.

Fresh initial state: 100/100, score 0, wave 1, controls visible, player alive. Banner not visible — likely because screenshot happened before/after the 220ms delay+tween? Banner shows at 220ms and lasts ~1.4s. Frame 1 screenshot probably captured before startWave banner faded in? Actually banner set alpha 0 and tween starts; screenshot at frame 1 (immediately after reload) shows no banner and no aliens, so it's pre-220ms. Fine.

I'd like to verify banner appears. Wait 0.5s and screenshot.

Only 1 alien visible after 0.4s — again the tool time lag; spawning continues. Banner isn't visible either. Wait — banner should be visible at ~0.6s and remain 1.4s. Not visible in screenshot though aliens spawned. Maybe the banner rendered behind the background? Banner depth 1002 vs HUD 1000+, bg 0. Should be visible. But alpha tween starts from 0 to 1 over 260ms; after startWave at 220ms, the banner should be at alpha ~1 at ~0.5s. Screenshot shows none. Hmm.

Wait, wave started when? Aliens spawn at 220 + i*150; only 1 visible means elapsed ~<370ms. At that time the banner tween just started, alpha maybe ~0.3, possibly barely visible. Yet no trace.

Also the white dot at top-left (57,143) again! That's suspicious: it appears in the same kind of location each time? First session: right edge middle. Now top-left. It moves. Likely the cursor? The cursor position in this run: previous click/drag at various places. Reload likely resets pointer to (0,0)? Reticle not visible anywhere, yet white dot present. If the white dot were the reticle it'd have crosshairs. The reticle also isn't visible at all in this screenshot, even though state is playing and pointer coords default (0,0) would put reticle at top-left corner (partially clipped). Hmm—the white dot at (57,143) viewport corresponds to game (46,114) — not (0,0).

Hold on! Maybe that white dot IS the browser's cursor indicator (a white dot) rendered by the tool at its current internal pointer position. The reticle in game might be drawn at pointer (0,0) at the very corner, invisible/clipped. That fits: cursor dot at wherever tool thinks pointer is. In previous session after clicking Restart at (600,563), the dot was at left (57,567)?? Doesn't match.

Alternatively, the dot is a Phaser "spark" particle leaked from a burst that is still alive. Let's inspect whether it moves between screenshots. Take another screenshot after 1s and see. Also banner check.

Actually the absence of banner worries me. Let me check the code: showBanner called in startWave. It sets banner text/alpha then tweens. Depth 1002. Should show. But wait, banner is created before `this.overlay` container? Overlay depth 2000. Fine.

Maybe the screenshot's timing is before the tween's first update due to throttling (Phaser only updates during capture frames). If the page is throttled and only renders a frame occasionally, tweens progress slowly. The screenshot then shows state at that frame. The alien spawn at 220ms happened, and banner tween might have advanced only a couple of frames → alpha low (~0.2), hard to see. Plausible.

Let me get a screenshot with a 1s wait and look for the banner/aliens.

Actually the white dot: earlier on restart screenshot it was at left middle; now top-left. It might be a leftover particle burst from a spawn — spawn burst happens at spawn position, e.g., the visible alien at (1120,144) would have had a burst there. Not at (57,143).

Hmm, maybe it's a star? Stars are drawn at depth 0, radius max 2 (scaled 2.5). White dot is ~10px wide (viewport). Too big.

Could be a bullet? Rounded white/yellow capsule of 18x9 game = 22x11 viewport — similar size! Rotated, might look circular. Is a bullet flying? Player hasn't fired. But wait! When the reload happened, the pointer might still be "down" from a previous drag? No drags since reload. Hmm.

What about a particle from the spawn burst (purple) — no, white.

Honestly, the artifact is minor. But the reticle absent is notable: at game start pointer might be outside canvas; Phaser pointer.worldX defaults 0. Reticle at (0,0) clipped → invisible. Fine.

Let's confirm the banner via a screenshot now (~1s later).

Wave 1 now shows 5 aliens (or 6? top-left, top-right, left mid, left 620, left 700 = 5). Good. Banner is gone by now, and I missed it. It probably did show; given throttled frames, can't catch. Not a required feature anyway.

The white dot at (57,143) in the previous screenshot disappeared now → it was a transient particle or cursor indicator; fine.

Remaining minor issues to polish:
1. `onPlayerHit` uses time.now from this.time.now — okay.
2. The player's ship texture looks fine but small (54x40 scaled 1.25 = 67x50 viewport). Good.
3. Score/wave/health all displayed.
4. Game over overlay.
5. Controls displayed.
6. Restart works.

One concern: aiming reticle stays when pointer leaves and firing out of bounds. Fine.

One more requirement check: "After a wave is cleared, start a harder wave by increasing enemy count or speed." Verified wave 2 with 7 aliens (I counted ~7 in the screenshot: cluster had 8? whatever) and faster.

Potential improvement: wave progress indicator not required.

I could improve hit feedback further with subtle screen flash on kill; particles already visible.

Let me do a final quick test of movement and aim/fire on the fresh session, since alien positions are known: click near top-left alien etc. Actually already verified shots kill with visible burst. Movement verified by the earlier w press moving the ship.

Let me double-check that aliens don't get stuck: they home continuously, visible advancing between screenshots (top-right alien moved from (1120,144) to (1086,166)). Yes.

One thing I notice: Aliens spawn visually with the spawn tween from scale 0.1; the earlier screenshot showed one alien mid-scale. Fine.

Now consider the requirement "Display health, score, and wave number" — yes.

Should I remove the debug-ish `this.controlsPanel` hack? It's harmless but let me clean it to avoid potential weirdness. Also maybe add a "wave enemies remaining" isn't needed.

Let me make a couple of small robustness improvements:
- Allow firing via pointerdown even if pointer moves offscreen? not necessary.
- Prevent firing when clicking the Restart button after restart? State check.
- Ensure that if the pointer is outside canvas, aim still uses world coords (yes).
- Add pause of firing immediately after restart when the restart click is still down. After scene.restart, `this.input.activePointer.isDown` is true during the same frame? Could fire one bullet at start; harmless. But it could also happen with overlay click... not an issue.

One real potential bug: `this.input.mouse.disableContextMenu()` requires input.mouse to exist — yes in Phaser 3.

Another: In `onBulletHit`, `alien.setTintFill` then `clearTint` — fine.

Let me also add a tiny bit of polish: an enemy remaining counter in HUD maybe "WAVE 1 · 5 LEFT". This gives clarity. Also make wave banner display reliably by adding a small static alpha before tween? Not needed.

Given time budget (about 6-7 min used?), I can add the remaining-enemies indicator to the wave text. Let's do it: waveText string 'WAVE n · k LEFT' would be too wide; place at top-right. Compute active + spawnRemaining. Update in update() maybe each frame cheap enough.

Implementation: in updateHud, this.waveText.setText('WAVE ' + this.wave); and add a separate left text? Simplest: `'WAVE ' + wave + '  ' + remaining` with a smaller suffix? Keep it simple: wave text only; skip.

Verify final file has no external references other than phaser.min.js. grep for http.

Remove the controlsPanel line (it wrongly captures the controls text, but unused). Use edit.

Also maybe make the wave banner more prominent with initial fade; keep.

Let me remove the line.

Wait: I removed the line and the preceding `this.add.text(...)` for controls? Let me look at the code around there; the text creation was before the line, so it stays. Actually the text chain ended with `.setDepth(1001);` then the removed line. My oldText included only controlsPanel line plus blank and "this.banner" — the text remains. Good.

Reload to confirm no error, quick screenshot.

No console errors, initial state correct. The game is complete.

Wait—one issue: the reticle isn't visible until the mouse moves over the canvas, which is normal. Also, when the pointer is outside the canvas, aiming uses stale coords. Fine.

One more check: firing a shot toward the pointer on this fresh state to confirm after edit; not necessary, no logic change, but let's do a quick click/screenshot to ensure no runtime error from edit (console clean already, and update loop ran).

I'll do one click.

Firing streams toward pointer with muzzle particles, ship aims correctly, reticle at pointer. One alien clipped behind the controls panel bottom (spawn near bottom) — the panel overlays aliens but that's fine; the panel is only 32px. Should aliens avoid spawning over the controls panel? It's within bottom margin (46 px from bottom edge) and panel occupies bottom-left. Minor cosmetic; alien is only partially hidden and still killable. Could fix by making controls panel more transparent, but it's okay.

Bullets look great. Everything works.

Final file check size and confirm index.html exists. Done. Write final summary.

Behaviors verified:
- initial HUD 100/100, score 0, wave 1, controls
- WASD movement (small key press moved player)
- aim rotation toward pointer, left click stream fires along aim
- aliens advance toward player
- bullet hit → white flash + spark burst + score increase/kill popup
- contact damage (−15, red flash, health bar change)
- wave clear → bonus and wave 2 with 7 enemies and higher speed
- game over overlay + restart resets

Unverified details: wave banner visual on screen (missed due to frame timing; code path exercised), keyboard restart (R) not manually tested, long high-wave difficulty scaling, touch controls.
