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.
thinking
The user wants a complete, self-contained Asteroids game in a single HTML file. Let me build this with: 1. Canvas-based rendering 2. Vector graphics (drawn with line segments) 3. Ship controls: rotate left/right, thrust, shoot 4. Screen wrapping for ship and bullets 5. Asteroids that split into smaller pieces when hit 6. Score and lives display 7. All CSS in `<style>`, all JS in `<script>` 8. No external resources Let me write a polished implementation.

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
Blank black screen throughout; JS error 'particles is not iterable' crashed the game entirely.
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.
