Thanks a lot for the honest review, it's funny you are the first one who found the secret mirror room, but it was definitely not supposed to crash lol. Did you get to find the dungeon in the library?
Yap yap, I found all the 3 spells actually, and another 4th one that was out of reach behind a grate. But as I said, I didn't really understood what they did.
As I said, I explored everywhere I could think of, I only gave up after I didn't had any other corner to check
