Script

Sure! Here's an example of a simple Snake game implemented in a single HTML file using JavaScript:

To play the game, save the above code into an HTML file (e.g., `game.html`) and open it in a web browser. You should see the snake game board and can control the snake using the arrow keys on your smartphone. The goal is to eat the red food and avoid hitting the walls or the snake's body. Please note that this is just a basic implementation for demonstration purposes and can be further enhanced with features like score tracking, levels, and better visuals.
