Teaching BASIC Gaming skills

My son has been playing minecraft for a while now with an Xbone controller and I think it’s time he learns how to mouse and keyboard. Just spent like 10 min with him and realized its much more complicated than I expected it to be (he’s 7). So, I think I’m going to have him go through this program as his gaming “homework”. Thought it was interesting and you may have someone you want to learn FPS basics, I’ll let you know how it goes.

There’s a video explaining what it’s all about, I timestamped the below video skipping the explanation and just showing the game/program.
