Sure! Here's an example of a simple fan game implemented as a single HTML file with JavaScript:
Fan Game
This game is a simple fan game where you control a player (represented as a blue rectangle) using touch events on a smartphone. The goal is to avoid colliding with a moving fan (represented as a red rectangle) for as long as possible. If the player collides with the fan, the game resets and the player is placed back at the starting position.
Note: This game is just a basic example, and you can certainly add more features, levels, and enhancements based on your requirements and preferences.
