Sure! Here's an example of a simple brick breaker game with two balls implemented as a single HTML file, incorporating JavaScript. You can play it on a smartphone or any web browser:
This implementation includes a canvas where the game elements are drawn: the bricks, balls, and paddle. You control the paddle using arrow keys or touch gestures on a smartphone. The goal is to break all the bricks using two balls and bounce them off the paddle.
You can copy this code into a single HTML file and open it in a web browser to play the brick breaker game. Please note that due to limitations of the text-based format, you won't be able to view the game graphics or interact with it as seamlessly as you would on an actual browser.
