Sure! Here's an example of a simple 2D game where you control a character and it farts every 5 seconds. The game is designed for smartphone operation and uses pictograms for visual elements. Save the code below in a single HTML file and open it in a web browser on your smartphone to play:
Make sure to save an image file named `emozi_himawari.png` in the same directory as the HTML file. You can create a simple image of a fart icon and use it. This code sets a character on a canvas that responds to touch gestures on a smartphone screen. The character farts every 5 seconds and the score continuously increases.
