Sure! Here's an example of a simple generative art game implemented as a single HTML file, using JavaScript and enclosed in script tags. It can be played on a smartphone and includes the use of pictograms:
This game randomly generates shapes on a canvas and continuously updates the canvas to display them. The shapes are simple colored rectangles, and each time the game is started, new shapes are generated. The game loop function runs at 60 frames per second to keep updating and redrawing the canvas.
You can further enhance the game by adding interactivity, user input, or additional features based on your specific requirements.
