This is a really cool game, and the sound design is really good, though I felt that the sound of the crystal clanking around was a bit too loud. The origami models were also pretty good.
The camera angle did feel a bit weird to me, I also noticed that there are no walls to the right or left of the player, and you can just see off into the vast emptiness.
If you ever expand the game, one thing that would be cool to see is different crystals that could be used to change the origami into different things instead of just the one.
