This 40 minute screencast recording & narration covers making a "Crazy Orb Rocket Robot" 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 controls an out-of-control space robot that must fly around and save floating penguins but avoid the space monsters. 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/16068041/#editor
