Criticism time!
1) The SOCs screw in the MR worse than Overdrive.
2) The sounds are as annoying as possible, especially the jumping sound.
3) Lightdash and homing were designed to give you precision in 3d analog games. Because SRB2 is not in analog, it's purpose has been served. When you'll be playing for the SA experience, SA mode will be on, and you'll have homing, lightdash, and analog anyway, proving them useless here.
4) The thok-item needs to be either more transparent or a different shade of yellow.
5) Run-on-water looks funny with his running frames.
6) Chaos spear has an icky sound effect.
7) I suppose he is overpowered, but when you combine homing, lightdash, water run, and ringslinger, he just feels clumsy.
8) He only has 2 running frames.
9) His spikes are too short.
10) It's just another shadow wad.
11) This is Donnyku 's work. Don't release v4 unless you decide to actually work on the spriting. Stealing means you look bad for not fixing his flaws, and for your lack of effort.
