I'm thinking I've missed a key somewhere or something, which is annoying, especially when I can hear chests I haven't opened because I can't get to them taunting me with their little bells from behind ledges and stone walls...
I'll explain where I'm stuck. I'm on the third floor, and went through the door at the east side of the room that warps you all around it. From here, there are two north entrances I can get through from either side, but neither one is the one that leads to the two chests I can hear. To the south there are three doors, but again, I can't get through the easternmost one because of a wooden key I don't have, and there's a chest behind that as well. To the south of the warping room is an entrance that leads me to a room with some enemies and a couple of switches I can't get at, as well as a door for the "Sky Team" (God Google Translate is terrible sometimes), and I don't have the key for that either. I've explored all the rooms upstairs that I could find and opened all the chests I could, but I get the feeling I'm missing something major. Please, if anyone could help me, I'd appreciate it...
