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 create a complete Asteroids game in a single HTML file. This needs to include: 1. A canvas-based game 2. A ship that can rotate and thrust 3. Shooting mechanics 4. Screen wrapping (edges wrap around) 5. Asteroids that split into smaller pieces when destroyed 6. Score and lives tracking 7. Procedural vector graphics (no external images) 8. Everything in one self-contained file with no external dependencies Let me build this step by step: 1. HTML structure with canvas 2. CSS for styling the game 3. JavaScript for game logic: - Game loop - Ship control (rotation, thrust, shooting) - Asteroid generation and splitting - Bullets - Collision detection - Score and lives - Screen wrapping I'll make it look like the classic Asteroids with a retro vector aesthetic.

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
Asteroids clone with ship, HUD, and drifting asteroids, but ship never rotates/thrusts/shoots in response to arrow keys in captured frames.
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.
