for some reason, when i walk through a door it makes a slime noise. However, it's only for that door in that particular direction. It doesn't harm the game or anything, it's just a minor bug.
Umm... On the Faust battle, I switched myself with one of the statues. Then I threw that hat back on the statue. The Spike wheels destroyed the statue (and the hat). I then switched myself with the statue. It went over the whole entire battle (without me in it; I was dead, I guess?????) and proceed to go past the exit and just show a bunch of skyline. I would fix this, as it reflects glitchiness on it. Still, regardless, great game!
Fixed the bug.
