Sure! Here's an example of a cat and mouse game implemented in a single HTML file using JavaScript:
This HTML file creates a grid-based game where a cat follows the mouse, and the player (mouse) needs to collect all the cheese to win. The game grid consists of cells displayed as div elements. The cat, mouse, and cheese are represented by background images. The cat moves towards the mouse on each turn, and when the cat catches the mouse, the game is over. The player can click on cells to move the mouse, and when the mouse collects all the cheese, the player wins.
