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, generative art is created by randomly generating either rectangles or circles with random colors on the canvas. The game continuously generates new shapes in each frame, resulting in a dynamic and ever-changing artwork. The game loop is started as the script is executed, and it runs until the page is closed or refreshed.
Feel free to customize the game to your liking by adding more rules, interactivity, or any other features that suit your idea of generative art!
