I have finally played the wad and there is small (a lot if you think of it) things I noticed, hope you can stand advance crits on your wad.
1. Hardly no shading what so ever (bad)
2. Shoes, gloves and gold bracelets not coloured properly (it needs to be if you want it to be good)
3. Quills not pulled down by gravity, they look a bit off on some frames (you need to follow physics)
4. His hair looks like sticks, make them more thicker (EX:

5.His energy is bright aqua, not blue (in my opinion)
6. gloves need the symbols on it.
Now things to add
1. Edit the ring slinger into an energy based sprite, just like SMS did in his/her wad
2. Jump higher (if it is possible )
3. When he hovers do the energy effect
That is all, thank you for your cooperation
