as far as puzzles go, I managed to get to the 2nd floor key, trying from both west and east wings, but I have 0 clue on how to make use out of the items you collect
doesn't seem like you can get the other key once you choose one wing key, which is weird since for there's that dark area needing east wing key and a flashlight you need west wing key to get
maybe I'm just dumb and can't see how things connect, gonna try running around some more
E: huh, framerate changes the speed of the game
E2: alright, so chests are randomised everytime, kinda sucks that the ability to solve puzzles depends on RNG
