Sure! Here's an example of a simple Pac-Man game implemented as a single HTML file using JavaScript:
To use this code, you would need to save the file as a `.html` file (e.g., `pacman.html`) and open it in a web browser. The game board will be displayed, and you can control Pac-Man's movement using the arrow keys on your device.
Please note that this is a very basic implementation of Pac-Man in HTML/JavaScript. It does not include any game logic, ghosts, points, or level progression. You can enhance it by adding additional features and functionality as per your requirements.
