Sure! Here's an example of a game where a square moves within a box and gets more corrupted over time. It will automatically teleport to the left side of the box when it goes off-screen, and it will also teleport if its corruption level reaches 10%. The game will be playable on a smartphone using pictograms for the square.
Corruption: 0%
You can save the above code in a file with an `.html` extension and open it in a web browser to play the game. The square will move within the box, and every 5 seconds, its corruption level will increase. Once the corruption level reaches 10%, the square will automatically teleport to the left side of the box.
