Script

Sure! Here's a sample Block Breaker game implemented as a single HTML file using JavaScript:

To play the game: 1. Save the above code in a new HTML file, for example, `blockbreaker.html`. 2. Open the file in a web browser (preferably on a smartphone). 3. Move the paddle left or right using the left and right arrow keys respectively (or corresponding touch-based controls on a smartphone). 4. The objective is to break all the bricks by bouncing the ball off the paddle. If the ball hits the bottom wall, the game is over. 5. Enjoy playing Block Breaker! Note: This is a simple implementation of the game and can be further enhanced with additional features, levels, and graphics as desired.
