Sure! Here's a simple implementation of a Pac-Man game using JavaScript enclosed in script tags within a single HTML file. The game can be played on a smartphone and it uses pictograms for visualization:
This implementation sets up a canvas element for rendering the game graphics. It defines a Pac-Man object with its position and size, then continuously updates and redraws that object within a game loop using the `requestAnimationFrame()` method. The Pac-Man moves to the right and wraps around to the left side of the canvas when it reaches the canvas boundary. You can enhance this implementation further by adding ghosts, dots, and additional gameplay mechanics.
