Okay, I confess. I needed the hints. I was on the right track, but math really isn't my forte. I see numbers and my brain gets confused and I become intimidated. But don't let that deter you, if you're like me. The game is not all about math.
This game was fun. Absolutely a joy. Learning the magical language was a snap, and most puzzles except the numerical one were totally intuitive. I spent a lot of the game not even worried about getting out - just trying things to see how far I could push conditions before I died. And you can die, but it's very easy to undo and carry on. Puzzles are so well-clued and I felt a real sense of accomplishment solving the ones I managed to do on my own. Well worth my time.
