Sure, here's an example implementation of a brick breaker game where the blocks move around. The game is built using JavaScript and HTML, enclosed within the script tags:
In this implementation, the game consists of a canvas where blocks, a paddle, and a ball are rendered. The blocks move around, and the player's goal is to bounce the ball off the paddle to destroy all the blocks.
The mobile touch event is used to move the paddle horizontally, and the game over condition is triggered if the ball reaches the bottom edge of the canvas.
Please note that this is a basic implementation to give you an idea, and you can customize and enhance it further based on your preferences.
