Very impressive, music is captivating, especially from the moment you got the golem Boss.
Spin theme reflected perfectly. Though I didn't really get controls. I mean, at first I tried slashing bosses and projectiles, but them I literally pressed one button to start spinning around - and nobody could do me any harm, while I kill them off. So it felt more like I watch a very cool small spectacle rather than play the game. Which is still awesome and it might just be me misunderstanding something.
Great job!
