Sure! Here's a simple implementation of a block breaker game using JavaScript in a single HTML file:

This code creates a block breaker game using a canvas element. You can control the paddle using the right and left arrow keys (or equivalent) on your smartphone. The goal is to break all the bricks by deflecting the ball with the paddle. Once all bricks are destroyed, you win the game. If the ball hits the bottom wall without being deflected by the paddle, you lose the game. Note: The code may not be optimized and could be further enhanced with additional features, levels, and styling, but it provides a basic working implementation of a block breaker game.
