Sure! Here's a sample code for a simple game where you have to chase a cat with a dog, implemented as a single HTML file using JavaScript:
Please note that you need to replace the `emozi_all/dog.png` and `emozi_all/cat.png` URLs with the actual URLs of the dog and cat pictograms you prefer to use.
To play the game, open the HTML file on a smartphone and touch the screen to move the dog. Once the dog gets close enough to the cat, an alert will be displayed congratulating you for catching the cat.
