Ok... so there is supposedly new content, except it's very, very, very bugged. After the hallway cutscene (which you only get if you *walk* into the hallway directly from your room, not if you go through Mirror Nexus) attempting to talk to Maxi just tells you that your inventory doesn't have enough room, even though you aren't even trying to pick anything up. (It is true that my inventory is full, though. I picked up all the potions I could waay early on, not realizing I even had an inventory size.)
Also, for some reason all of the buttons on the bottom right say that they keybind is Ctrl now.
