Sure! Here's a simplified version of Pac-Man implemented as a single HTML file:
In this implementation, the game board is a 10x10 grid represented by HTML div elements. Pac-Man is controlled using arrow keys on a smartphone, and the goal is to collect food items scattered across the board. The player's score increases whenever Pac-Man consumes a food item.
Note that you would need to provide the actual image files for Pac-Man, the food, and the ghosts (as mentioned, pictograms can be used) and update the image URLs accordingly in the CSS.
