Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript:
In this example, the game starts with a countdown timer of 60 seconds and a score of 0. The player needs to click on a pictogram displayed on the screen to earn points. The pictogram is randomly positioned on the screen, and the player has to earn as many points as possible within the time limit. Once the time is up, the game ends and the final score is displayed. You can replace "emozi_all/game.png" with the actual URL or path to your desired pictogram image.
