I bought this after seeing someone (I think it was the game's creator - excellent advertising) use it to solve Advent of Code problems on Reddit. It's really good, a very accessible introduction to how computers work. There were a couple of kinks in the UI that need to be ironed out like zooming and scrolling, but conceptually, the drag-and-drop UI for building circuits is excellent. I didn't get that far before life got in the way and I put it down - I think I was stuck on the adding bytes section. I'll have to pick it back up.
