Script

Sure! Here's an example of a simple Block Breaker game implemented as a single HTML file using JavaScript:

To play the game, simply copy the code into a new HTML file and open it in a web browser (on a smartphone). The game canvas will be displayed, and you can control the paddle using the left and right arrow keys (or tapping on the screen). The objective is to break all the bricks using the ball and paddle, without letting the ball touch the bottom of the screen. Good luck and have fun playing!
