Sure! Here's an example of a simple FPS pixel game about interacting with objects, implemented as a single HTML file:
This game sets up a simple scenario where the player, represented by a red square, can move around using arrow keys on a smartphone. The objective is to collect blue objects, represented by blue squares. When the player collides with an object, it is collected and removed from the game. The console will log the message "Object collected!" for each object collected.
Feel free to modify and enhance the game further as per your requirements!
