Fun 3D puzzle platforming!
I would have preferred if the game didn't reset after inputing the wrong sequence. I replayed various times trying to get the good ending, but didn't manage to find the hint on the orientation, or maybe I found it but I didn't get the clue.
On the other hand I had quite some fun trying to speedrun and sequence-break on the later playthroughs. I think that the gravity mechanic and your level design are a good combination for this kind of playstyle.
Also in my opinion the fog could be used better. It created that otherwordly atmosphere which I liked but also made some jumps more difficult, which is a positive if you're going for that.
