Sure! Here's an example of a simple generative art game implemented as a single HTML file using JavaScript:
In this game, the canvas is used to display a continuously changing generative art pattern of randomly placed pictograms. The available pictograms are defined in the `pictograms` array, and the `generateRandomPictogram()` function selects a random pictogram from the array.
The `draw()` function clears the canvas and then randomly draws 100 pictograms at different positions on the canvas using random colors. The game loop starts by calling `setInterval()` to continuously update and redraw the canvas every 1 second.
You can save the above code into a single HTML file and open it in a web browser to play the game on a smartphone. Enjoy!
