Sure! Here's a simple idle game implemented as a single HTML file using JavaScript, enclosed in script tags:
Idle Game
In this simple idle game, there are two types of resources represented by pictograms. By clicking the "Gather" button associated with each resource, the corresponding resource count on the page increments. The game loop, started by `setInterval`, runs every 1 second for processing any further logic while the game is idle. For now, it just prints a message to the console.
You can play this game by opening the HTML file in a browser (preferably on a smartphone for assumed operation). As you click the "Gather" buttons to collect resources, the counts will increase and the game will continue to process in the background.
