An absolutely crazy system with an awesome amount of possibilities, I managed to break it by trying to make a compact assembly line while writing cat, but overall it was really fun. Even if I was pretty stuck on trying to make a T of all things for the longest time.
The setup and all is really cool, one big thing though is it seemed to be sort of random as to what letters became a question mark? For example the L that I turned into the left side of a T couldn't be turned anyway to become the right side of a T by reflecting it beforehand and then rotating. Which felt kinda weird? Since it works the one way and not the other.
Overall though, a really cool system idea and a lot of levels I didn't manage to complete but will definitely be coming back to.
