We need to create index.html containing canvas game. Use JS for game loop, input handling, drawing vectors. We'll output final content via write tool. Need to write file. Let's craft full HTML. Simplify: Use requestAnimationFrame loop, ship object with position, velocity, angle, thrust. Wrap around. Asteroids as objects with size (3,2,1) radius, velocity, polygon points (maybe random shape). On bullet collision, split size>1 into two smaller asteroids. Score, lives displayed. Controls: Arrow left/right rotate, up thrust, space fire. Implement straightforward. Write index.html.

The **Asteroids** game has been fully implemented in a single self‑contained `index.html` file. It includes: - Canvas rendering with procedural vector graphics. - A thrust‑and‑rotate ship, bullet firing, screen edge wrapping. - Asteroids that split into smaller pieces when shot. - Score and lives UI. - No external assets or network requests. You can open `index.html` in a browser to play.
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.

EVALUATION
Ship and drifting asteroids render as vector shapes with score/lives HUD, but ship doesn't visibly respond to inputs.

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.
