Build a playable Asteroids game on a canvas: a thrust-and-rotate vector ship that shoots and wraps around the screen edges, splitting asteroids into smaller pieces, with score and lives. Procedural vector graphics only, no external assets.

The user wants me to build a complete Asteroids game in a single HTML file. Let me create a self-contained game with: 1. A vector-style ship that can thrust and rotate 2. Shooting mechanics with bullets 3. Asteroids that split into smaller pieces when hit 4. Screen wrapping (objects that go off one edge appear on the other) 5. Score tracking and lives 6. All procedural graphics (no external assets) I'll need to implement: - Canvas-based rendering - Ship physics (velocity, acceleration, rotation) - Bullet management - Asteroid generation and collision detection - Game state management (playing, game over, etc.) - Score and lives display - Sound effects (optional, using Web Audio API for procedural sounds) Let me write this as a complete, playable game.

The file has been created. Let me verify it exists and is complete.

The file has been created successfully. It's a complete self-contained Asteroids game with: 1. Vector-style ship that can thrust and rotate 2. Shooting mechanics with bullets 3. Asteroids that split into smaller pieces when hit 4. Screen wrapping (objects that go off one edge appear on the other) 5. Score tracking and lives system 6. Procedural graphics (no external assets) 7. Sound effects using Web Audio API 8. Start screen and game over screen 9. Particle explosions when asteroids are destroyed The game is fully playable by opening index.html in a browser.
Done! I've created a complete, playable Asteroids game in `/tmp/ws/index.html`. The game features: **Controls:** - Arrow keys or WASD to rotate and thrust - Space to shoot **Features:** - Vector-style ship with thrust animation and rotation physics - Screen wrapping - objects exit one side and reappear on the opposite side - Asteroids split into 2 smaller pieces when shot - 3 asteroid sizes: large (50px), medium (25px), small (12px) - Score system: 20 points for large, 50 for medium, 100 for small asteroids - 3 lives with invulnerability period after respawning - Particle explosions when asteroids/ship are destroyed - Procedural sound effects using Web Audio API - Starfield background rendered procedurally - New waves spawn as you clear asteroids (increasing difficulty) To play, open `index.html` in any modern web browser.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Menu screen leads into functional Asteroids gameplay with ship and asteroids responding to keyboard input, lives decreasing indicates collisions/game logic.
Vision grade · anthropic/claude-sonnet-5
MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
