Sure! Here's an example of a simple game about monkeys and balloons using HTML, CSS, and JavaScript:
Monkeys vs Balloons
In this game, you can control the monkey at the bottom of the screen by dragging your finger across the screen. The monkey's goal is to pop the balloons that appear randomly from the top. The game will continuously create balloons that fall towards the bottom, and you need to move the monkey to pop them by touching the screen.
