Sure, here's an example of a simple Block Breaker game implemented as a single HTML file with JavaScript code:
// Enclose the JavaScript code within
To play the game, you can copy and paste the above code into a text editor and save it as a `.html` file. Then, open the file in a web browser (preferably on a smartphone for a better experience). The game should start automatically, and you can use the left and right arrow keys or on-screen buttons to control the paddle and hit the ball to break the bricks.
Note: The game uses a basic alert for displaying game over and winning messages. You can customize the appearance and behavior of the game by modifying the HTML, CSS, and JavaScript code as per your preferences and requirements.
