Sure! Here's an example of a simple game called "Duet Pets" implemented as a single HTML file:
In this game, there are two players represented by pictograms (player1.png and player2.png). The objective is to control the ball using the arrow keys or touchscreen gestures to prevent it from hitting the walls.
Note: Make sure to provide appropriate image files for `emozi_rabbit.png` and `emozi_apple.png` in the same directory as the HTML file.
Please note that this example is just a starting point, and you can further enhance and customize the game as per your requirements.
