Sure! Here's an example of an idle game implemented as a single HTML file using JavaScript and enclosed in script tags. This game will allow you to accumulate points over time by clicking on a pictogram.
Idle Game
Points: 0
Click the pictogram to earn points!
Points per click: 1
In this game, you have a pictogram that you can click to earn points. Each click increases your points by the `pointsPerClick` value, which is initially set to 1. Additionally, points accumulate over time even if you're not clicking the pictogram, at a rate of `pointsPerClick` per second.
The game displays the current points, points per click, and a brief instruction. The `setInterval` function is used to call the `accumulatePoints` function every second, updating the points automatically.
Feel free to replace the `emozi_all/pictogram.png` with any other pictogram image you prefer. Additionally, you can modify the game mechanics by adjusting the `pointsPerClick` variable or adding more features to the game.
