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

This code creates a simple block breaker game where the player controls a paddle to bounce a ball and break bricks. The game is played on a canvas element using JavaScript for game logic, ball movement, collision detection, and rendering. The player can control the paddle using the right and left arrow keys on a smartphone. The game ends when the ball falls below the paddle, and a "GAME OVER" message is displayed before reloading the page.
