Sure! Here's an example of a simplified Pac-Man game implemented as a single HTML file using JavaScript and enclosed in script tags:
Pac-Man Game
In this example, you can control Pac-Man's movement using the arrow keys on your smartphone. Pac-Man is represented by a yellow circle (pictogram), and it moves within the game board represented by a square. The game loop continuously updates Pac-Man's position based on the chosen direction and renders it on the screen by adjusting the CSS `left` and `top` properties of Pac-Man's element.
Please note that this is just a simplified version of Pac-Man and doesn't include any enemies or collectibles. The purpose is to provide a basic understanding of how the game mechanics can be implemented using HTML, CSS, and JavaScript.
