Overall very fun game. It worked really well as a puzzler, the physics was fun and I had a good time. Level 11 had me stumped for a bit until I figured out how to get the strength power up down without dying. I think this game has a lot of potential, with the simplistic controls it could work really well as a mobile game.
If you wanted to improve, I suggest adding a timer to encourage people to speed run. Maybe a rating per level based upon how many rotations happened or the time taken to complete it. I also suggest making the rotation less sudden. It could be very disorienting, maybe freezing the objects and doing a quick rotation would work better.
Overall super fun game and I'm glad I played!
