Sure! Here's a simple implementation of the classic game Pac-Man as a single HTML file, with JavaScript enclosed in script tags:
This implementation sets up a game board with a Pac-Man character represented by a div element with the class "pacman". The Pac-Man starts at the top-left corner and can be controlled using the arrow keys on a smartphone. The movement is restricted within the boundaries of the game board.
It's important to note that you'll need to replace the "emozi_all/pacman.png" with an actual image file of the Pac-Man pictogram for it to display properly.
