Sure! Here's an example of a simple generative art game implemented as a single HTML file using JavaScript and enclosed in script tags:
In this game, each frame of the animation generates a random shape (either a circle or a rectangle) with a random position and color. The canvas is continuously cleared and the game loop is called repeatedly using the `requestAnimationFrame` method. This creates an animated generative art experience. You can open this file in a web browser on your smartphone to play the game and see the generative art in action.
