Sure! Here's an example of a simple game called "Baby In Purple" implemented as a single HTML file using JavaScript:
In this game, you can control a "baby" character using the arrow keys on a smartphone. The baby image is represented by a pictogram stored in `emozi_all/game.png`. Use an actual baby pictogram image to replace `'emozi_all/game.png'` in the code. The baby moves 5 pixels in the corresponding direction each time an arrow key is pressed. The game loop continuously updates the baby's position and redraws it on the canvas.
Please note that you'll need to have an actual baby pictogram image file, named `emozi_all/baby.png`, in the same directory as the HTML file for the image to be displayed correctly in the game.
