Sure! Here's an example of a simple generative art game implemented as a single HTML file. The game is designed for smartphone operation and uses pictograms.
This game utilizes HTML canvas and JavaScript to create generative art. The script generates a random pictogram from the given pictograms array at the position of user clicks or touches on the canvas. The canvas is set to match the screen dimensions and it is styled to be centered with a light gray background. Feel free to modify the pictograms array or add more to suit your preferences.
