Sure! Here's an example of a simple Atari Pong game with lasers and 18 balls implemented as a single HTML file:
To play the game, you can open the HTML file in a web browser on your smartphone. The game consists of two paddles (controlled by the player and the computer) and 18 balls. The objective is to prevent the balls from hitting your paddle by moving it up and down using the ArrowUp and ArrowDown keys on your smartphone's keyboard. The computer-controlled paddle will also try to block the balls.
