Sure! Here's a simple game called "Mom vs Rat" implemented as a single HTML file:
In the above code, the game consists of a canvas element where the game events are rendered. The mom and rat pictograms are drawn using the `drawImage` method. Tapping on the rat moves the mom towards it, and the score increases whenever mom catches the rat. The game continuously updates and renders the game state using the `update` function and the `requestAnimationFrame` method.
Please note that this code assumes you have "emozi_rabbit.png" and "emozi_all/rat.png" images in the same directory as the HTML file. You can replace them with your desired pictograms.
