Sure! Here's an example of a simple game where money falls from the sky and you have to collect it to increase your score. It is implemented as a single HTML file and uses JavaScript. It is designed for smartphone operation and uses pictograms to display the game elements.
Money Rain Game
In this game, money icons fall from the sky, and when you collect them by touching/clicking on them, your score increases. The score is displayed in a score bar at the top. You can adjust the rate at which money icons spawn by modifying the `setInterval` argument in the `startGame` function, and you can replace the money icon by replacing the `url('emozi_all/game.png')` with the path to your desired money icon.
