I've created a complete Snake game in a single HTML file with no external dependencies. The game includes all the requested features: - Canvas rendering with a black background and green snake - Arrow key controls for movement - Growing snake tail when food is eaten - Food collection system with random placement - Score tracking that increases as you eat food - Game over detection when hitting walls or self - Restart functionality with a button The game runs completely locally without any network requests, using only HTML5 Canvas and JavaScript. The snake grows longer each time it eats food, and the game speeds up slightly as your score increases. To play: 1. Use the arrow keys to control the snake 2. Collect the orange food squares to grow and increase your score 3. Avoid hitting the walls or yourself 4. When the game ends, click the "Restart" button to play again The game is fully self-contained in one file and should work in any modern browser.
