Sure! Here's an example of an aging simulator game implemented as a single HTML file using JavaScript. Please note that the use of pictograms may require additional image assets, which are not included in this text-based response.
Aging Simulator
In this game, you will see three kids represented by pictogram images (`emozi_all/game.png` in this example). Every second, the ages of the kids will increase by 1 year, and the corresponding images will change based on their age. The `getKidImage()` function can be modified according to your specific pictogram assets.
