Sure! Here's an example of a simple Pac-Man game implemented as a single HTML file using JavaScript and pictograms:
Note: In this example, we assume you have a pictogram for Pac-Man available and its URL is specified in the `background` property of the `.pacman` CSS class. Make sure to replace `'emozi_all/pictogram.png'` with the actual URL of the Pac-Man pictogram you want to use.
This is a basic implementation that shows Pac-Man moving horizontally across the game container. You can further enhance the game by adding additional game elements, logic, controls, and scoring systems as per your requirements.
