Pretty neat! Only thing I would say is that I couldn't figure out how to toggle the spin mode because whenever I did it seemed like it wasn't doing anything. It turns out that I was still trying to move during it which was messing with the spin (I'm guessing because of the physics from moving). I would try to make it so you can move while spinning without it messing up the spin and see how well that feels. Maybe give a stamina bar while spinning so it doesn't feel too OP and you have to manage it some. Either way, could be the start to something fun!
