Sure! Here's an example of a simple game where you control a character represented by a square, and other squares will throw boomerangs at you. This game can be played on any device with a web browser.

To play the game, you can embed the above HTML code into a file with a `.html` extension and open it in a web browser on your smartphone or any other device.
In the game, use your finger to control the square character. Avoid getting hit by the moving square boomerangs. If your character gets hit, an alert message will appear and the game will reset.
