This game is clearly brilliant. Unfortunately, I am not! Some of the puzzles I could figure out entirely on my own. Some I could understand what was asked of me but couldn't quite get there without the hints. And then there's the ones like level 45 which I cannot for the life of me comprehend. I'm sure it's very simple and obvious to smart people, but this was my limit.
Also! I really felt like some horrible math monstrosity was stalking me in the background while I banged my head
against the number walls. Which certainly added to the experience. But maybe that's just my take on things.
