The procedural generation was nice! I also greatly appreciate the arrow leading you to the exit after defeating the Great Wizard because I felt so lost the entire time. One thing I would add is better feedback when you kill something (maybe a rewarding sound or animation). Sometimes it would be difficult to tell if I killed one of the teleporting wizard guys.
I saw your reply on this, but it was hard to figure out how the theme tied in. Overall a very well done and polished game.
