Sure! Here's an example of a single HTML file that implements a simplified version of the Pac-Man game using JavaScript and pictograms:
This code sets up a Pac-Man game where you control Pac-Man using arrow keys on your smartphone. Pac-Man can eat dots, avoid or squash ghosts, and eat a mega fruit to gain power. The game ends if Pac-Man collides with a ghost without having the power or if Pac-Man eats all the ghosts on the board. The game will be played inside a `<div>` element with the id "game-container".
Please note that this implementation is just a basic example and does not include all the features and complexities of the original Pac-Man game.
