I need build single index html canvas game. Should inspect cwd.

I'll implement polished playable. I have browser tool. Make sure keyboard testing via key. Game should opening movement firing. Should have visual design procedural canvas perhaps neon CRT navy stars, score. Should self contained. Could do 960x680 canvas scaled responsive, HUD outside canvas or canvas. Should game states. Controls displayed, restart button. Should have collisions, destructible bunker per grid material. Alien formation moves horizontally reverse descend at edges. Alien fires toward player. invuln brief flicker. Win game over overlays. Pause perhaps P. fire rate 300 ms. Projectile life 1.4 sec, bounded. All required.

Design stylish retro dark terminal with canvas full. Main panel centered 960 x 650 and HUD above, instructions below. Canvas logical 960x620. Cannon y 565. Aliens top 110; 10 cols x 4 = 40. Bunkers y440 etc. If 40 clear maybe tests alien shot tricky. Can expose no test API ideally. Alien bullet hitting bunker visible damage. I can run via keyboard.

Canvas rendering: background stars; grid; aliens crisp rectangles procedural different rows; bullets. Bunkers composed cells 6x6, classic shape using pixel arrays 18x10 cells cell4, 4 bunkers width96. Collisions projectile with cells based rect; removing local 3x3 around impact. Should have shots pass through gap. Ensure removal robust. Alien shot spawn only if bottommost in column and cooldown. Enemy shots aim loosely toward player (dx limited). Speed 220. Aliens overall horizontal movement at 25 px/s plus speed based destroyed. Edge descent 18. Shots relative.

Collision: bullets list objects friendly etc. Player bullet radius2. On update segment perhaps simple rect collision. Bunker collision before aliens? since bullet upward passes bunker. Enemy bullets can hit bunkers and player. I should only process once. Player bullets colliding with enemy bullets optional.

Player rectangle 38x22. Alien grid rect cell 48x36 alien 30x22. Start x ~180 for 10 cols total 462. y 100. Move bounds. Edge reverse: formation positions alien.x etc, fleet dir. When next crosses boundary, reverse and all y +=18. Simpler after move if min<28 or max>932 then undo x shift, dir *= -1, y+=20. Fine.

Game over aliens reaching player zone if alien bottom >= player.y-12. lives reset. Hit invulnerability 1600ms. life decrement and brief shield. If 0 game over. During invulnerability bullets pass through player? Should not repeatedly damage, perhaps remove bullet without life? "brief protection from repeated damage." Could remove shot on collision and no life? Fine. visual shield.

Restart all state. RAF and delta capped. Start immediate opening. Buttons restart. Click canvas focuses perhaps. prevent space scrolling. game paused on blur perhaps not necessary. Accessibility.

Should sound? procedural WebAudio no external optional, nice. But audio keyboard could work. I can create AudioContext on input and simple sound. Not needed but polish. Add mute button? no.

Should have high score? localStorage not necessary perhaps scoring. Score once via alien.dead and bullet dead. Particles and floating feedback "+100". Game state status text. HUD values. Canvas overlay win. Restart button always.

I'll create.

Should test browser.

Looks good. Should test movement firing opening. Browser key action perhaps key down/up? definition key text. Usually browser key {"text":"ArrowRight"} sends press short. Can use type? I'll use key ArrowRight hold? key tool likely keyboard press. Movement only while pressed means brief no visible. Could use keyboard repeated? Could test via key text. Should have screenshot after movement. Fire Space.

Interesting time passes significantly per tool ~10sec? Lives down 2. Bunker damage yes. Formation moved. Key short no movement visible. I'll restart and immediately fire.

Click at wrong x,y? Button screenshot y763 yes x1037. But game over remains means perhaps click event after? Actually button not visible screenshot due viewport 800 footer perhaps y764 but game overlay ends y799. Click at x1040 y764 on canvas not restart! Footer below viewport? Initial screenshot button absent indeed. Should scroll.

Scroll not changing? Body align center min-height but content > viewport? It should scroll perhaps screenshot top changed? header disappeared yes scroll. Should further.

Now click restart.

Reset verified pristine. I'll fire. Space short; center shot will hit bunker top center at x600 y540 (canvas actual bunker center x600). Bunker center has shape material top y432+ etc so shot hits. I'll repeatedly shoot 10 times to gap and alien. Browser key perhaps press. Time tool screenshots instant? use key.

Again tool waited ~10 sec perhaps each key waits 10s! Life down. Formation right, descended? y same but reverse edges. Shot not visible. It hit bunker likely but center bunker no damage? Third bunker center x685 corresponds 562? Logical scaling positions offset. Player center 600 corresponds logical480. Bunkers logical 352 and 562, nearest x?? Canvas screen x95 + scale1.01*480 =600. Bunker positions logical352 screen 450, 562 screen662. Player x480 between bunkers! So player shot passes between no bunker, should hit alien but aliens moved right significantly. At firing immediate aliens x207..702 moving, center logical480 hits col5 x482 if not moved. But by time shot traveled aliens moved and may miss. Score 0. Should movement and firing reliably. Main issue time tool latency? Browser interactions each screenshot after many sec. Could use repeated key Space with 10? Could use browser type? keys press event immediate and update only one shot. To score need move cannon under alien current then fire. Hard given time. Could perhaps test using direct runtime via inspect no eval. Browser only supports actions. Could fire then screenshot perhaps tool waits. Score not guaranteed.

I should improve game to avoid idle game over too fast? Opening tool delays but real game fine. Required "brief protection". Current invulnerable drawPlayer returns entirely before shield so shield not visible because returns! During blink alternating; okay. But enemy shots very fast death while stationary. Classic. Perhaps I want initial enemy fire 0.8 and frequency .8 etc 3 lives within 20 sec. Browser tool took ~10 sec per action. Fine.

Potential bug: state set won in update before shots removed but okay. Restart click focuses canvas and keys states perhaps space remains? On restart via space, keys.Space=true then restart, next frame fire. okay.

Should check movement. Keypress right too short. browser key supports text perhaps "ArrowRight" presses and releases instantly, update not. Could browser drag? no. Could use repeated key with down impossible. type perhaps text "d" keydown/up same. No direct evaluate. I can inspect perhaps browser inspect gives runtime? likely DOM only. I could use CDP via bash? Browser environment perhaps no remote. But verification can be brief accessible. Should test movement by key hold using key text "ArrowRight" no delay options. Could type repeated "dddd..." yields each press perhaps updates enough. Try restart then key Space immediate perhaps aliens reset and bullet shot. Should have scoring by shooting while moving left/right. I could use many shots via keyboard autorepeat? key tool text "Space" perhaps keyup. Use browser key " "?? same.

Potential collision bunker flaw: Shot can tunnel through cells? Speed540 dt max .033 =17.8 px, cells 6, condition y within6 => possible tunneling! Player shot crossing bunker can skip over material because collision checks after moving. Same alien bullets speed235 dt7.8 <=12 good. Player shot can skip thin bunker top rows and alien height25 with step18 okay. Bunker only6 pixels cells condition12 high, step18 can tunnel sometimes. Should implement swept collision or smaller dt for projectile. Could collision with previous y. Store prev y and check material along segment. Important requirement shots remove bunker reliably. Current player shot might tunnel, though random across. Should fix robust segment collision using sampling in shot update from previous to current or collision use segment. easiest in update shot, before movement set ox oy then after move, damageBunker with interpolation? modify damageBunker(shot, oldX,oldY) and test samples based distance/4. Could use for shot path each sample and if hit set shot x/y at impact. Or update fixed timestep globally to 1/120 accumulation. Current frame dt .033, player speed. Simpler damageBunker uses shot.px py and distance loop. Each shot move assign s.px=s.x etc. Function loop over bunkers and sample shot segment to find cell. Should have exact impact and explosion radius. Could iterate samples n=ceil(distance/3), for each set shot.x etc, scan all bunkers, then return. If no hit restore new current. Since damageBunker currently checks current. Rewrite function moderate. This ensures. Also alien collision can tunnel horizontal? bullet 18 vs alien25 safe. Player bullet hits alien fine.

Should consider visual screenshot bunker seems black grid due scanline overlay and cells gap1, good.

Perhaps add touch controls? not required. Footer below fold but controls displayed still user can scroll. Canvas fits width and height ~620 but screen total 800. On 1200x800 footer below. Fine. Could compact to fit initial? Desired display controls required, if below fold technically displayed in page but not initial viewport. Browser initial screenshot controls not visible. Better responsive viewport height scaling to show controls on common 800. Current canvas 960/620 at width1010 gives height652, plus header64, hud48, paddings 22 etc total~842. Perhaps max width based on viewport height: cabinet width:min(100%,1010px, calc((100vh - 175px)*1.548)); CSS min supports. At 800 gives625*1.548=968, canvas height625, total~780, controls perhaps still below. Current canvas display includes hud 49 and screen pad. Should set width min(100%, 960? calc). If viewport 800 target canvas height570 => total header61 + screen hud50 + canvas570+16 + footer50 + body44 =791. width882. So .cabinet width:min(100%,1010px, calc((100vh - 225px)*1.548)); at800 =890. Then canvas height575. good. At smaller height perhaps too narrow. Could use @media(min-width:700px) and (max-height:900px) .cabinet{width:min(100%, calc((100vh - 190px)*1.548),1010px)} body padding14 header etc. But not needed game functionality. Yet visible controls useful. I can adjust body padding 16, cabinet width:min(100%, 1010px, calc((100vh - 170px)*1.548)); at800 975, canvas630 total still 800? I'll accurately initial screenshot top title y37, screen y89 to beyond 800. Footer y? after scroll max 88, button y758. Total content bottom 780 at scroll88 =868 document. Should reduce 68. Canvas height current652. Should reduce canvas by68 => width reduce105 to905. So calc (100vh - 175px)*1.548 gives 967 only reduce43 => canvas -28 insufficient. (100vh - 215px)*1.548 =905 yes. Total document800. At900 gives1060 cap1010 so fits since content height868 <900. Great. Set width min(100%,1010px, calc((100vh - 215px)*1.548)); But on phone height800 width390 min 390, no issue. On landscape height500 gives441 width tiny but usable. Could set only min-width 651 to avoid weird mobile. @media (min-width:651px){.cabinet{width:min(100%,1010px,calc((100vh - 215px)*1.548));}} CSS min with negative at very low could invalid? ignore. This improves. Controls footer and header at initial.

Should test easier, perhaps implement pause when window blurred? Tools no. No.

Scoring points currently row3=25, row2=50, row1=75,row0=100 good.

Lives restart resets.

Projectile life bounded, enemyFire bounded by bottom and lifespan.

Alien reaching player zone sets lives0; requirement game over yes. Usually lives not zero but okay.

Player cannon along bottom. Good.

Perhaps fix damage collision and shield drawing perhaps shield return prevents shield during half blink expected. Fine.

I'll edit cabinet and damage function.

Should reload initial new fit.

Looks great all fits. I'll fire opening immediately after reload. Tool reload screenshot initial time perhaps only 0.1 sec. key space then screenshot after ~? It has been 10 sec each. I'll do multi? Could browser key with Space then immediate screenshot separate.

No score. Player shot x600 in between bunkers but alien moved right to550+, opening bullet fired then misses because by time reached aliens shifted? Only 25 px/s, bullet travel .8 sec alien20 px, alien width34, starting x550? Initial col5 x552.5? player x480, initial col5 482; after20 px still within17? x502 vs480 diff22 >20. So miss narrowly. Should alien horizontal speed lower or player shot faster to allow straightforward center shot. Player shot speed540 travel from540 to220=.6 sec, shift15, plus radius gives20 => initial diff15, should hit perhaps at y240 alien col5 497 vs480 diff17 exactly borderline. Why no score perhaps by fire time aliens already advanced due tool? reload screenshot initial x342 to810; after key screenshot x550 etc due 10 sec. At key actual press perhaps happens after wait? Screenshot shows 10 sec after. At firing initial yes. Could be bullet hits alien and score0 no. Perhaps bullet fired when keydown then keyup, yes.

Player shot starting x600 screen corresponds logical480. Initial alien centers screen344+55*.94 increments: col5=602, exactly. after .6sec ~14 px => hit. Could hit bottom alien row3 at y327? bullet y~? from logical540 to227 .58 sec, alien x497, diff17, rect half17+3=20, yes. Should score. Unless enemy shot cost lives then game reset? no score stays. Perhaps shot fired at some delay when alien formation already shifted due browser key action waiting before actual key? Hard.

I can make shots faster 650 and aliens speed20 initial. But game playable challenge fine. Verification can use many firing/movement. Perhaps holding space with repeated key tool only one shot per call. Could send "Space Space" not. browser key text can be "Space" only. Use key "Space" repeatedly tools sequential each 10 sec and likely game over. Could use type text " " triggers perhaps. I could make cannon shots slight homing? Not requested and would be odd. Could use wider player bullet (3), fine.

Perhaps collision with aliens uses object x,y center yes. Bunker damage check before alien. Since between bunkers no issue. Wait player x600 screen and bunker logical352 screen481,562 screen675. Shot x480. Bunker1 right edge397 screen524, bunker2 left517 screen635. gap. good.

Should test score via center shot immediate after restart perhaps restart button sets state then click next Space has tool 10 sec so aliens not at center. Reload then key should initial but perhaps page reload action returns after initial screenshot then time passes before next command. 10 sec between tools due model latency perhaps game continues while I think! Yes analysis time real perhaps. So impossible opening firing across separate calls. Could combine actions? multi_tool parallel not sequential and same browser unsafe. browser action type could send keys? no. Could add click to fire and restart? not. I can test through scripted browser via bash using Playwright installed? inspect node_modules.

Require from absolute /app/pipeline/node_modules/playwright. Can run scripted tests headless chromium, console, use page keyboard down with waits. Browser existing might be chromium. I can use node script inline no files. Test actual. Use chromium launch perhaps executable. I'll run Playwright file:// and keyboard events. Should score and reset. Could inspect canvas pixel not state internal due closure. DOM score, lives, screenshot. For opening formation, page reload then immediately keyboard down right 300ms up then space, wait1000, read score. At player moves right93 to573, alien initial col7? x592, after20 px to612 diff39 perhaps miss. Better fire without move first and separately movement. Test center shot immediate.

Center shot definitely not hitting. Why? Bullet firing center initial, perhaps alien coords. Should debug via screenshot timed. Read /tmp image.

Move works (player x710 vs center600). Center shot at x480 logical but alien col5 initial482, should hit. Why score0? Bullet life 1.25 enough from540 to92 distance448/540=.83. Collision aliens bottom row at227. speed. Perhaps shot collides with bunker? At x480 logical between bunker1 [307,397] and bunker2[517,607], gap120. no.

Alien x after .6=497, diff17 exactly. rectHit uses x+r>o.x-w/2 strict. 480+3 >497-17=480 =>483>480 yes. y conditions. should.

But potential bullet hits alien at different column? okay. Wait alien speeds 25, after .6. y bottom227. Bullet at227 at .583, alien x496.6. yes.

Perhaps page keyboard.press('Space') triggers keydown and keyup within same frame, update never sees keys.Space true! firePlayer only in update based key state, no keydown immediate. Browser tool likewise. Real human key >16ms usually but keyboard.press instantaneous may be missed. Should fire on keydown directly for responsiveness, with keys space for autofire. Add if code Space and state playing && !repeat firePlayer(); Then test. This also meets. This is clear problem. Add.

Now scripted test.

Great. Should inspect bunker damage from player or alien. Could screenshot after opening shot perhaps score25, alien removed. I'll use script to fire at bunker center by moving player x from480 to352, need left .413 sec. Then fire hits bunker. screenshot after perhaps .3 sec bullet around bunker or impact. Could compare pixels manually. I can run screenshot after 0.6 sec and inspect. Also test alien reversal descent via screenshots or pixel difficult. Could instrument only visual no state. I can use canvas image comparisons. Requirements test alien motion, screenshot after1sec different. I already saw. Should win/gameover perhaps accessible behavior not necessary full. But should verify lives loss with wait. Restart. Could test player bounds by hold left2s screenshot at boundary. projectile lifetime etc code.

Potential issue initial player shot firing immediate and holding keys.Space remains until keyup but fine.

Should test bunkers persistent gaps and shots pass: script fire at bunker repeatedly. Start center move left to352, fire every350ms 6 shots to carve. enemy shots may hit. Could inspect. No need exhaustive. But requested specifically shot hitting bunker or alien visible damage or score. score verified. Good.

Should browser tool after fix perhaps quick key space then score.

Should have final browser perhaps game over from thinking. Could do key space score now likely miss. Already scripted verified. Perhaps run thorough Playwright test for life and restart after bunker. Could also ensure all required no external. Check index no external. Good.

Potential serious collision: aliens fired toward player but enemyFire picks bottommost via column array order column[column.length-1]. aliens pushed row ascending, filtered dead retains order, yes bottommost highest row at end. Good.

Alien shots collide with all bunkers including gaps correct.
Bunker damage hit detection current function samples from previous to new. For first step starts inside alive cell if shot spawned inside bunker? player not.
Player bullets after hitting bunker shot dead and continue main, good.
Particles update even overlay, okay.
Game over zero lives. Alien reaching zone sets lives0, okay.
State won when aliens cleared sets won after shots loop. Score update.
Restart initial formation etc. Stars don't reset irrelevant.
Player position resets.
Controls A/D via e.code. Great.
Fire rate 0.28 enforced with immediate fire + update; holding works.
Projectile lifetime 1.25 enough. enemy3.
Movement bounded 30..930 and player half21 so 9 margin.
Canvas scaling coordinates logical okay.
No third party.

One issue on restart by click while space held keys Space could remain true only if restart via Space sets reset and next frame fires; okay.
State overlay drawn but update shots no after state, good.
Bunker cell destructive shape restarts.

Could add explicit status "GAME OVER" in DOM for tests? Canvas only acceptable. DOM text won't show but game visual. No need.

Now run automated checks with screenshot alien kill and bunker damage. I can use screenshot after opening shot 750ms to see +25 and hole, then read.

9 sec no life because player under bunker protected. That's okay. Now read bunker screenshot.

Bunker2 damaged central vertical huge from 3 hits good. This verifies. Formation movement okay.

Could test game over and invulnerability with script no bunker: player center gap so gets hit in ~? previous browser after10 sec lost lives. Script at center wait15 sec state game over. Perhaps verify. Win state harder 40 kills. Could use gameplay holding space and moving? Not necessary "remaining unverified" response can mention win/gameover not full playthrough. But I should perhaps verify game over via wait 20 sec no input, and aliens reaching zone after much longer not. Automated 30 sec perhaps. I have time. But no need; brief pass.

Should browser respond after modifications console clear. I have browser console none. Could use restart current to pristine then respond. Browser currently perhaps game over due time. I'll call click restart visible 994,775.

Should respond concise mention file, features and checks and unverified. User didn't ask explanation. "Built index.html ... Verified in Chromium: ... Full win/game-over playthroughs not manually completed." But game over seen via browser earlier. I saw game over, life. Win unverified. Alien reversal observed after10s and descend? screenshot after10s aliens x... y same perhaps edge descent from initial y92 to111? In initial first browser after ArrowRight aliens at y perhaps245 same? Browser screenshot initial after reload aliens top92. after10 sec first screenshot aliens top245? Actually same? second game over aliens at~251, so yes. I can say checked formation motion, firing, score, bunker damage, restart, console. Full win and alien breach not play-tested. Fine. Ensure final file only index.
