Amazing work! I liked how this game looks, it's very cool with a cooler concept
There's some points i want to highlight:
Knockback is too strong, atleast for me, sometimes when I get hit I fall in the spikes and need to start again, it's frustrating
The blades looks cool, but it's a bit slow
Some hitboxes are bigger than I though, it make some jumps harder than expected
Despite that I liked it a lot, I know you worked hard on it, i keep it up! :D
