Sure! I can help you create a generative art game in a single HTML file using JavaScript. Here's a basic example to get you started:
Explanation: This code sets up a canvas element and defines a few configuration variables. It then generates random shapes (filled rectangles) on the canvas using the `generateShapes()` function. The `updateCanvas()` function clears the canvas, generates new shapes, and repeatedly calls itself using `requestAnimationFrame()` to create an animation loop. The game starts by calling `updateCanvas()`. You can customize this example by adding more shapes, changing colors, or using different shapes like circles or lines.
You can further enhance the game by adding interactivity or game logic according to your specific requirements. Feel free to modify the code as per your needs to create an enjoyable generative art game.
