I wasn't very good at it since I'm not used to this style of movement, so I died in the platforming section. I also got stuck in walls when trying to save myself. I'm not sure about the mechanic where you have to give up to save your highscore, maybe a more seamless transition between loops would have been better.
The monsters were pretty funny looking and in theme. And the loop projectile reminded of the blue shells from Mario Kart.
I think it was a decent idea, especially the idea of enemies staying around for the next loop if you don't kill them which links the loops a bit more.
