The Snake game has been built and saved to `index.html`. Here's what's included: **Features:** - **Canvas-based gameplay** with a 400x400 pixel play area - **Arrow key controls** (also supports WASD) - **Growing tail** - snake grows when eating food - **Food spawning** with collision detection to avoid spawning on the snake - **Score tracking** with points for each food eaten - **High score** saved to localStorage - **Game over screen** with final score display - **Restart button** to play again **Visual Details:** - Neon green snake with gradient body and eyes on the head - Red glowing food with pulsing animation - Dark background with subtle grid lines - Snake eyes that change direction based on movement - Increasing speed as score goes up (every 50 points) **Game Mechanics:** - Snake cannot reverse direction (prevents instant death) - Wall and self-collision end the game - Speed increases gradually to increase difficulty Open `index.html` in a browser to play!

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.
