Hey man, Alex Rose here. Thanks a tonne for playing. I did watch all the way through!
First, by the way, you misread the description at the start about the physics. It actually says "except without super tight physics", not with. :P
Cool find with the fairy not turning into the wizard! It was because you jumped all the way over that switch without touching it. The transformation sequence activates when you touch that spot.
Also, I was really, really hoping you'd notice. Look at 20:56
, there's a door in the ceiling that's shut. Now look at 27:46
. The ceiling is open! And then at 30:04
, corpses had appeared, where people died in the shortcut route.
That route leads to the final battle where you may or may not turn Super Saiyan :P .
Anyway, I really enjoyed watching your playthrough. Thanks a lot!
