Build a playable Space Invaders game on a canvas: a player cannon that moves and shoots, a descending grid of aliens that advance and fire back, destructible bunkers, score, and lives. Procedural graphics only, no external assets.
thinking
We need to write a single HTML file with canvas Space Invaders. Must be self-contained, procedural graphics only. We'll write HTML with canvas, style, script. Implement player cannon, aliens grid, bunkers, shooting both ways, collision, score, lives, game loop. Use requestAnimationFrame. Keep simple but functional. We need to write to index.html in workspace. We'll create file using write.

thinking
We have written the file. Need to ensure it's correct. Provide final answer with path.
The game is ready in **/workspace/index.html**. Open this file in a browser to play Space Invaders – it includes a movable cannon, descending alien grid, alien fire, destructible bunkers, scoring, lives, levels, and win/game‑over screens, all drawn procedurally on a `<canvas>` with no external assets.
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
Space Invaders renders with aliens, bunkers, cannon; game reaches Game Over during drag/wheel tests but keyboard input works fine.
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.
