Sure! Here's an example of a simple Pac-Man game implemented in a single HTML file using JavaScript:
This HTML file creates a game container with Pac-Man (`pacman`) and a ghost (`ghost`) represented as colored circles. The game allows the player to move Pac-Man using arrow keys, while the ghost moves randomly. Collision detection is implemented to detect when Pac-Man and the ghost overlap.
Please note that this implementation is very basic and serves as a starting point. You can modify and enhance it further to create a more complete and enjoyable Pac-Man game experience.
