Sure! Here's an example of how you can create a simple generative art game using JavaScript and HTML, suitable for smartphone operation:
The code above creates a simple generative art game where random shapes (circles, rectangles, or triangles) of random colors are drawn on the canvas. The shapes move randomly around the screen, and new shapes are generated every few seconds. Shapes that go off the screen are removed from the game.
You can customize the code further to add additional features, such as user interactions or scoring mechanisms, based on your requirements.
