Enemy animations are really great, especially the guy who sends shockwaves out. The fact that enemies are only greyed out when killed is kind of odd.
I was initially a bit confused by the weapon range. It felt like it wasn't possible to swing to the left because of the way the scythe was positioned. I also agree that the range is a bit short, and the jump is kind of janky.
The dodge was cool. i-frames is a big plus! I would've maybe tied dodge velocity to a sine-wave to get speed-up and slow-down at the start and end.
All in all quite good! Especially the way you've used the sprites
