Script

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

This code will create a small block breaker game where you control a paddle using the arrow keys to bounce a ball and destroy bricks. The objective is to destroy all the bricks to win the game. The score will be displayed on the screen, and if the ball touches the bottom edge of the canvas without hitting the paddle, the game will be over. You can play the game on a smartphone by opening the HTML file in a web browser.
