Sure! Here's a simple generative art game implemented as a single HTML file, containing JavaScript code enclosed in script tags:
In this generative art game, the canvas element is used to draw circles of random colors at random positions on the screen. The `getRandomColor()` function generates a random hexadecimal color code, and the `drawCircle()` function is responsible for drawing the circles on the canvas.
When the page loads, the `generateArt()` function is called, which generates and draws 100 circles on the canvas. Each time you refresh the page, new circles with different colors and positions will be generated, creating a unique generative art experience.
Note: This game can be played by opening the HTML file in a web browser on a smartphone.
