This is a really cool game mechanic! After a couple of runs I got used to how to play; it feels like you have to choose each move carefully. I like that you have the option of making things difficult for yourself at the start in order to get more rewards.
The music and art were great and feels like a really polished game. The only thing I'd say is that it can be quite complicated for the first 1 or 2 runs, so maybe a slightly longer tutorial could help. (also one tiny nitpick is that the level 1 bone seems to flip about its vertical axis when switching directions, but the other tiles don't do that.)
Overall I really liked this game, it's a super original idea and executed really well.
