Sure! Here's an example of a game where you control a color-changing ball using sin and cos functions to move around within the game area. The game is implemented as a single HTML file, enclosed in script tags, and written in JavaScript.

This game will display a canvas with a ball that changes color and moves around using sin and cos functions. You can run this code directly in a browser, and the ball will start moving and changing color. It should work well on a smartphone too.
