I've created a complete Space Invaders game in a single self-contained `index.html` file. Here's what's included: **Features:** - **Player cannon**: Green ship that moves left/right with arrow keys (or touch on mobile) and shoots with spacebar - **Alien grid**: 5 rows × 10 columns of procedurally drawn aliens with different colors/points by row - Top row: Yellow (30 points) - Middle rows: Magenta (20 points) - Bottom rows: Cyan (10 points) - **Descending movement**: Aliens move horizontally, drop down at edges, speed increases per level - **Alien shooting**: Random alien bullets fire at player - **4 destructible bunkers**: Arch-shaped shield blocks that degrade on impact (3 health stages) - **Score system**: Points based on alien type - **Lives system**: 3 lives, game over when depleted - **Levels**: Beat all aliens to advance; win after level 3 - **Starfield background**: Procedural animated stars **Controls:** - ← → Arrow keys or touch to move - SPACE to shoot - ENTER to restart after game over Open `index.html` in a browser to play.

EVALUATION
Space Invaders renders with aliens, bunkers, ship, HUD; aliens auto-descend and shoot but player ship and shields don't visibly respond to input.
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.
