Sure! Here's an example of a simple Pac-Man game implemented as a single HTML file, including JavaScript and using pictograms:
This implementation creates a 5x5 game grid using CSS Grid. The Pac-Man, dots, and power pellets are represented using pictogram icons. You can control Pac-Man using the arrow keys on your smartphone's keyboard. The goal is to eat all the dots by moving Pac-Man around. Once all the dots are eaten, a congratulatory message will be displayed.
