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.

The user wants a complete Space Invaders game in a single index.html file. Let me build this with: 1. HTML structure with canvas 2. CSS for styling 3. JavaScript game logic including: - Player cannon (movement + shooting) - Alien grid (descending, advancing, firing back) - Destructible bunkers/shields - Score tracking - Lives system - Procedural graphics (pixel art drawn on canvas) - Game states (start, playing, game over) - Sound effects using Web Audio API (procedural) Let me design this carefully: **Player:** - Moves left/right with arrow keys or A/D - Shoots with spacebar - 3 lives - Drawn procedurally as a cannon shape **Aliens:** - Grid of 5 rows x 11 columns - Different types per row (different point values) - Move side to side, drop down when reaching edge - Speed increases as more are destroyed - Fire randomly **Bunkers:** - 4 bunkers between player and aliens - Made of small blocks that get destroyed by bullets - Both player and alien bullets destroy bunker blocks **UFO:** - Occasional UFO flying across top for bonus points Let me write this comprehensively.

Let me verify the file was created properly.
Let me verify the file is in place:

The user wants me to continue. I already built the Space Invaders game and wrote it to index.html. Let me check if there's anything the user might want - they said "Continue" but I haven't received any follow-up question or feedback. The file is already written and present. Let me just confirm everything is good. Actually, looking back, I already provided a full response with "Done! `index.html` is ready..." - the user just said "Continue" which seems like they might want me to test it or verify it works, or perhaps they accidentally sent "Continue" as a prompt. Let me check if the game actually works by reviewing it, or perhaps they want me to serve it or test it somehow.
The file is already complete and present at `/tmp/ws/index.html`. Here's what's included: **Features:** - **Player cannon** — moves with ← → or A/D, shoots with Space/↑ - **55 aliens** in 5×11 grid (3 types: squid=30pts, crab=20pts, octopus=10pts) with 2-frame pixel animation - **Descending aliens** that speed up as fewer remain, drop rows, and fire zigzag bullets - **4 destructible bunkers** with pixel-level damage from both player and alien fire - **Mystery UFO** that flies across the top for bonus points (50–300pts) - **Lives system** (3 lives, respawn with blink), score, high score (localStorage) - **Multi-level** — aliens get faster, start lower, and shoot more each wave - **Particle explosions**, screen shake, twinkling stars - **Sound effects** via Web Audio API (shoot, explosion, alien march, UFO) - **Start screen** with score table and controls, game over screen with stats Open `index.html` in a browser to play!

EVALUATION
Functional Space Invaders with player ship, alien grid, bunkers, score/lives, and game-over screen; visuals look clean.
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.
