This 19 minute screencast recording & narration covers making a "Block Breaker" game in the Scratch programming environment.
Scratch is a free programming educational tool from MIT for kids and teens. It can be used in the browser or downloaded to your Windows, Mac, or Linux PC. https://scratch.mit.edu/
In this game, the player bounces a ball to break blocks at the top of the screen. The viewer can follow along as the narrator puts the program together one code block at a time from scratch.
You can play this game yourself at https://scratch.mit.edu/projects/11719281/#editor
