Sure! Here's an example of a simple idle game implemented as a single HTML file using JavaScript and pictograms:
Idle Picto Game
Click the pictogram to earn points!
Score: 0
In this game, the player can earn points by clicking the pictogram, which represents a clickable area. The score is displayed on the screen, and each click adds 1 point to the score. Additionally, the player earns points automatically over time (1 point per second) with the help of the idle feature.
Note that the pictogram image is assumed to be named "emozi_all/pictogram.png". You can replace it with any image of your choice to fit your game concept.
