AMAZING!
I've never seen a game like this before. It's cool that you have to use the environment to rotate yourself in the correct position but also the same environment provides a challenge by purely trying to traverse it. I would've liked to see a part where you are confined in a smaller space where you almost lack the proper surface to turn but you have to figure out really how to do it. Or like a room where you have to turn yourself in a direction and then a keyhole at the end of a maze that you have to traverse without getting bumped. Or creating areas that halt the rotation so you have to think ahead of time and can't just solve everything by furiously wiggling the mouse (although my game is just that so I should't say anything :P).
All around amazing game, also cool looking. It was fun while it lasted, I wanna play more of it, please continue :D
