Script

Sure! Here's a simple implementation of a block breaker game using HTML and JavaScript, enclosed in script tags within a single HTML file:

This code will create a block breaker game that can be played on a smartphone. The game is rendered on a canvas element and uses pictograms (black rectangles) for the bricks and game objects. The paddle can be controlled by touching and dragging on the screen, and the ball will bounce off the paddle and bricks. The objective is to break all the bricks using the ball without letting it fall off the bottom of the canvas. The game keeps track of the score and lives, and displays a Game Over or Congratulations message accordingly.
