Sure! Here's an example of an idle game implemented as a single HTML file with JavaScript using the script tags:
Idle Game
In this game, the player earns coins by simply playing. Every second, the `earnCoins()` function increments the `coins` variable by 1 and updates the displayed number of coins. The game also displays an image of a coin and a text showing the current number of coins.
Note: To make this example work, you need to have an image file named "emozi_all/coin.png" in the same directory as the HTML file.
