Script

Sure! Below is a sample implementation of a Block Breaker game using JavaScript and HTML. It is enclosed in script tags within a single HTML file. You can copy and paste the code into a new HTML file and open it in a browser to play the game.

This implementation uses canvas to create a game where you control a paddle to bounce a ball and break bricks. The paddle can be moved left and right using the arrow keys or by touching the screen on a smartphone. The game ends when the ball touches the bottom wall without hitting the paddle. The score is displayed on the canvas, and a "Congratulations" alert is shown when all bricks are broken. You can easily customize the game by modifying the visuals, levels, and gameplay mechanics.
