Sure! Here's a simple example of a generative art game implemented as a single HTML file with JavaScript:
This simple generative art game uses a canvas element to display randomly generated pictograms on touch input events. Each time you touch the screen, it generates a new set of pictograms in random positions on the canvas. You can customize the `pictograms` array with your desired symbols.
To play, open the HTML file on a smartphone and start touching the screen to see the generative art change.
