I've successfully created a complete Snake game in a single HTML file with all the requested features: 1. **Game Canvas**: The game plays on a responsive canvas with a grid background 2. **Controls**: Arrow keys to control the snake direction (up, down, left, right) 3. **Game Mechanics**: - Snake grows when it eats food - Score increases by 10 points per food item - Game speeds up slightly as you eat more food - Collision detection with walls and snake's own body 4. **Game States**: - Start screen - Active gameplay - Game over screen with final score - Restart functionality 5. **Visual Features**: - Snake with head differentiation and eyes that follow direction - Attractive food with shine effect - Score and high score display - Responsive design that works on mobile and desktop - Smooth animations and visual effects 6. **Additional Features**: - Difficulty selection (Easy, Medium, Hard) - Pause/resume with spacebar - High score persistence using localStorage - Game instructions and controls displayed The game is fully contained in one HTML file with no external dependencies. You can run it directly in any modern browser. The game includes visual polish with gradients, shadows, and smooth animations to create an engaging experience.

MEASUREMENTS
