Sure! Here's an example of a simple Pac-Man game implemented in a single HTML file using JavaScript:
The code above creates a basic Pac-Man game where you can control Pac-Man using arrow keys on your smartphone. The game consists of a black game board with a yellow Pac-Man, red ghosts, and a blue maze. The levels are defined in the `levels` object, and you can add more levels if needed.
Note: This is a simplified implementation to provide a starting point. You can expand and enhance the game further with additional features, such as collision detection, scoring, multiple levels, etc.
