Heya! I'm adoring this game, the aesthetics are lovely, but I think I've come across a some kind of glitch? There's no way I could find to move past the Piston Room, because the box is blocking the way.
There is actually an opening in the fence right next to the boxes that you are able to jump down to the floor below.
It's okay if you couldn't find it though, I'll try to make it more noticeable. I'm sorry for the confusion.
