I dont know if this is a bug or what, but after stage VI (6) on The Pit it gives you a message that reads "New Magic Unlocked at the shop" and well i had bought magic before that and when going to the shop to find the "New Magic" nothing changed at all... any ideas?
Found interesting bug get a light bridge blue at end yellow on wall. Then remove blue when you are on the light bridge off of yellow. You get stuck floating weirdly
