Sure! Here's a sample code for an auto Atari Pong game with lasers and 12 balls implemented as a single HTML file using JavaScript:
This code sets up an HTML canvas element and uses JavaScript to draw the game elements, including the paddles, balls, and lasers. The player can control the paddle on a smartphone by touching and moving it vertically. The balls bounce off the paddle, walls, and each other. When a ball hits the paddle, lasers are fired from that position. The lasers move towards the left side of the canvas. The game runs in a continuous loop using `requestAnimationFrame`.
