Graphics are coherent, for the most part, doors excepted. They look like they don't belong in the universe. The animations are a bit dodgy as they trigger at unexpected times. For instance, going down slopes causes the character to fall indefinitely until you stop.
Music doesn't look. Sounds are repetitive as very few samples are used.
The only relationship with theme is when I went backwards in the "So Close" area. I didn't see any other parts of the game, because after collecting the puzzle pieces and going to the area where I could used them, I tried the obvious option, then all of the combinatorics. I the retried all of them again, one by one, entering and leaving the trigger collider. Nothing happened. I then quit.
