Sure, here's an example implementation of a Block Breaker game using JavaScript and HTML:

This HTML file contains both the game logic and drawing functions necessary for a simple block breaker game. The player uses the left and right arrow keys (or the 'A' and 'D' keys) to move the paddle and hit the ball to break the blocks. The game is won when all the blocks are destroyed, and it is lost if the ball touches the bottom edge. Note: This is a simplified implementation and may not be optimized or have advanced features. Feel free to modify and enhance it further according to your requirements.
