Another weird thing about the Polyhedron: I remember Klara(?) said at some point that she doesn't get why everyone says the Polyhedron is made of glass and mirrors, when it's obviously paper. Isn't it a weird thing for her to say? The Polyhedron you can climb into does have a paper texture but it's also transparent if you look closely. The *other* Polyhedron though is obviously made of glass (and by the way, its spike is more obvious). I don't know if this is relevant in some way, or it's just the game joking about itself (like it happens when Burakh hears that some thieves escaped climbing fences and pipes and he replies "I can't climb fences..."
)
