Sure! Here's a simple game implemented as a single HTML file with JavaScript. It utilizes generative art and can be played on a smartphone. I've used pictograms where possible to enhance the visual experience.
This game generates random circles with different colors on a canvas. When you tap/click on a circle, its color will change to a new random color. The goal is to create your own generative art by interacting with the circles. You can play this game on your smartphone by opening it in a web browser. Have fun creating beautiful patterns!
