Sure, I can provide you with a simple game called "Ball Hunt" implemented as a single HTML file with JavaScript. Please find the code below:
In this game, green squares represent bushes, and you can move the blue player square using your mouse or touch on a smartphone. When you click or tap on the screen, a ball will be shot, and if the ball hits any bushes, the corresponding bush will disappear. The current score will be logged in the console for each successful hit.
Feel free to save the code as an HTML file and open it in a web browser to play the game. Let me know if you have any further questions!
