The user wants a Space Invaders game. Let me build a complete, polished implementation with: - Player cannon that moves left/right with arrow keys and shoots with space - Grid of aliens that descend and fire back - Destructible bunkers (shelters) - Score system - Lives system - Procedural graphics (all drawn on canvas, no images) - Game over / win conditions - Restart capability Let me write this as a single self-contained index.html file.

The file has been written. Let me verify it works by checking the structure and then provide a summary. The game includes: - Player cannon (drawn procedurally with a cannon body, turret, barrel) - 5 rows × 11 columns of aliens in 3 types (different colors/points) - Aliens move side to side, drop down when hitting walls, speed increases with waves - Aliens fire back (homing-ish missiles) - 3 destructible bunkers with arch shapes, pixel-based destruction - Score display, lives display - Explosions/particles - Starfield background - Menu, pause (P key), game over, win states - High score tracking Let me verify the file is correct by doing a quick check.
The game is written. Here's what's included in the single `index.html`: **Gameplay** - 5×11 grid of aliens in 3 types (green = 10pts, yellow = 20pts, orange = 30pts) — they march side-to-side, drop when hitting walls, and speed up each wave - Player cannon moves with ← → (or A/D), shoots with Space, has a cooldown - Aliens fire homing-ish missiles back at the player - 3 destructible bunkers with arch cutouts — destroyed pixel-by-pixel by both player and alien fire - Score, lives (hearts), wave counter, high score - Particles/explosions on hits - Starfield scrolling background - Pause with P **States**: menu → playing → paused → game over / win → play again **Procedural graphics**: every sprite (cannon, aliens, missiles, bunkers, explosions) is drawn with canvas primitives — no images, no external assets. Open `index.html` in a browser to play.

EVALUATION
Only a static start menu is shown; clicking Start Game was never triggered so no actual gameplay occurs.
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.
