Sure! Here's a simple game where 100 squares throw boomerangs at each other. Each square can be controlled using touch gestures on a smartphone. The game is implemented as a single HTML file, enclosed in script tags, and written in JavaScript. Here's the code:

To play the game on a smartphone, open the HTML file in a web browser on your device. The game starts automatically. You can tap on any square to make it move in a random direction. The squares will continue moving until you tap on them again to stop their movement. Have fun playing the boomerang game!
