Sure! Here's an example of a game where the player controls a cube-shaped character using touch input on a smartphone. The goal is to pass through various obstacles by tapping and holding on the screen to make the cube jump.
You can save the above code in a file with a .html extension and open it in a web browser to play the game. The cube character will automatically start moving, and you can tap and hold on the screen to make it jump and avoid the obstacles.
Note: This is a basic implementation and does not include advanced features such as scorekeeping or level progression. Feel free to enhance the game as per your requirements.
