Sure, here's an example of a game that meets your requirements:
When you load this HTML file in a web browser (on a smartphone or any other device), a screen will appear with emojis bouncing around really fast. Every time you click on an emoji, it will clone itself and display a notification in the browser console.
Note that the speed of bouncing and cloning can be adjusted by modifying the `setInterval` duration in the `startGame` function. Feel free to experiment with different emojis or customize the game further to suit your preferences.
