Sure! Here's an example of a simple generative art game implemented as a single HTML file using JavaScript. This game allows you to create unique artworks by clicking on the screen. It uses pictograms as the artwork elements.
Note: The following code snippet needs to be saved with the .html extension and opened in a web browser to play the game.
To play the game, open the saved HTML file in a web browser on your smartphone. Whenever you tap on the screen, a random pictogram will appear at the corresponding location, creating an artwork. You can keep tapping to create more pictograms. The artworks will be displayed on the screen, and you can restart the game (clear the artwork) by simply refreshing the page.
