The file is present and complete. I've built a full Space Invaders game. Let me summarize for the user.
`index.html` is a self-contained Space Invaders game (procedural pixels only, no network). **Play:** Enter to start · ←/→ or A/D to move · Space/W to fire · P to pause **Included** - Cannon that moves and shoots (one shot on screen) - 11×5 alien grid that marches, drops, speeds up as ranks thin, and fires from the lowest invader in a column - Four destructible bunkers (cell-based craters from both sides) - Mystery UFO with random bonus points - Score, high score (saved locally), lives, waves - Title, pause, wave, and game-over screens - Tiny square-wave SFX via the Web Audio API (no assets)
