Script

Sure, here's an example of a simple block breaker game implemented as a single HTML file using JavaScript. It is designed to be played on a smartphone and uses pictograms for visuals.

This block breaker game includes a paddle, a ball, and blocks that need to be destroyed by bouncing the ball off the paddle. The player controls the paddle by dragging their finger across the screen on a smartphone. The objective is to destroy all the blocks without letting the ball fall off the screen. If the ball falls off the screen, the game is over and a "Game Over" alert is displayed. You can copy and save this code as an HTML file and open it in a web browser to play the game on a smartphone.
