This ticks a lot of the boxes of an amazing jam game: solid mechanics, stunning visuals, puzzles that aren't too hard but not a pushover either. Close it off with great atmosphere where everything is really well tied together.
A minor thing for sure, but really liked the way you guided the player (introducing the box for the first time) without having a giant arrow pointing at it. Beautiful, beautiful work at all fronts. My favorite game of the jam so far!
