I thought the main mechanic was pretty cool! It was certainly different than I expected. I also liked the art, the player character was very cute and the little walk animation was great.
The weakest part for me was the boss fight, I don't know if it was intentional but every time I reset after dying, the boss just rushed me and I went down to 1 HP. Eventually I just cheesed it and stood below one of the spinning blades to kill it, but it didn't feel that rewarding.
Overall, strong concept that just needs a bit more attention to the final part to have a satisfying experience!
