Here's an example of a simple game implemented as a single HTML file using JavaScript:
In this example, the game consists of an image of Barbie in the center of the screen. When the Barbie image is clicked, a function called `applyMakeup()` is executed, and the image is replaced with another image representing Barbie with makeup.
You can replace "emozi_rabbit.png" and "emozi_apple.png" with your own pictogram images for the Barbie character and the Barbie with makeup, respectively.
Please note that this is a basic example to show the basic functionality of a game. You can extend it further by adding additional features, levels, or interactions based on your requirements and specifications.
