Sure! Here's an example of a simple Pac-Man game implemented as a single HTML file using JavaScript and enclosed in script tags:
This code sets up a simple Pac-Man game using HTML canvas and JavaScript. You can control Pac-Man using the arrow keys on your smartphone, and Pac-Man will move around the canvas, wrapping to the opposite side if it goes off-screen. The game loop continuously updates and redraws the Pac-Man character on the canvas.
Please note that this is a very basic implementation and lacks other features such as ghosts and pellets. You can enhance the game by adding those elements and implementing their behaviors based on your requirements.
