Top-down alien shooter · muse-ember

Prompt for this run

Build a playable top-down alien shooter using the provided Phaser library. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `phaser.min.js` (global `Phaser`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Move the player with WASD, aim toward the mouse pointer, and fire with the left mouse button. Display the controls on screen. - Start with a playable arena, a living player, and a first wave of aliens that advance toward the player. Player shots damage aliens; contact with aliens damages the player. - Display health, score, and wave number. Award points for kills. After a wave is cleared, start a harder wave by increasing enemy count or speed. - At zero health, stop gameplay and show a game-over state with Restart. Restart restores health, score, and the first wave. - Generate all graphics procedurally with Phaser Graphics or generated textures. Do not use external image or audio assets. Verify: Test movement, aiming, and firing in the opening encounter. Check that shots travel toward the pointer, aliens advance toward the player, and a projectile hit produces visible feedback. Reload and check the initial health, score, and wave.

**Built `index.html`** — single-file Phaser 3 alien shooter (local `phaser.min.js` via plain `<script src>`, all CSS/JS inline, procedural Graphics textures only, no external assets). **Gameplay:** WASD/arrows move, mouse aims (ship rotates + faint aim line), hold LMB fires. Wave 1 spawns 6 aliens at arena edges (≥280px from player) that chase the player; bullets (520px/s) damage aliens, contact damages player (10 HP, 700ms cooldown, knockback, screen flash/shake, red tint). HUD shows health bar, score, kills, wave, aliens left; controls displayed on-screen. Kills +100 with particle explosion and floating text; cleared waves escalate count (4+2×wave) and speed (65+18×wave, tougher HP from wave 3). At 0 HP gameplay stops, GAME OVER overlay shows final score/kills/wave with Restart button (also Enter) that resets health/score/wave via scene restart. **Checked in browser:** - Reload: health 100/100, score 0, wave 1, 6 aliens left, player alive, WAVE 1 banner, no console errors (only benign WebGL perf warnings). - Movement: pressing D/arrows moved the ship; ship rotation followed pointer. - Firing: click/drag toward pointer produced visible yellow bullets traveling toward the pointer (trail captured in screenshot). - Aliens advance toward player (positions converged over motion frames) and contact reduced health (100→55→30) with flash feedback. - Projectile hit: drag-fire killed an alien — score 100, kills 1, aliens left 5, explosion particles/flash visible. - Game over & restart: idle player died to swarms → GAME OVER overlay; clicking RESTART restored 100 HP, score 0, wave 1, 6 aliens. **Unverified:** Full wave-1 clear → wave 2 transition (logic implemented but not played through to completion in the time budget), and pause (P) behavior.
