Nice, I am a fan of this idea and have been trying to figure out the right way to engage my niece in computers in a real way. One of my biggest concerns from seeing how it impacted my stepdaughter (now in college) is how kids are not learning how general purpose computers work and are becoming too comfortable existing entirely in restricted environments like iPads and Chromebooks. With my niece, I'm taking more active measures to ensure she learns how things actually work.

I bought the full version because I'm not a fan of in-app purchases in things marketed at children, and I'll give it a playthrough myself first to make sure it fits the bill. One of the upcoming projects we're going to do together is to build a mechanical keyboard. I'm also going to build a PC with her and try to teach her the basics so she can explore mostly uninhibited on Linux.
