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

To play the game, simply save the above code in a `.html` file, open it in a web browser (preferably on a smartphone), and the game will start automatically. Use the left and right arrow keys (or swipe gestures on a smartphone) to move the paddle and prevent the ball from falling off the bottom. The objective is to break all the bricks by hitting them with the ball. Enjoy!
