Sorry I'm late to this release.
I love what you did to Normal Sonic.  I think this moveset Is more suitable for him, good work. 
Here's some feedback:
- Overhead Kick and Quick Overhead Kick have the wrong commands in the readme (Hold ~F, D, Z)
- Ex Overhead Kick easily becomes a grab because they've the same buttons.
- I like that Sonic can run past his opponents but it would be cool if he could use that ability to crossup opponents.
- When Sonic runs and jumps, he always overshoots past his opponent.  This makes his run through opponent ability obsolete IMO.
- His Spin Dash could go farther IMO.
- Just a suggestion: Have you ever considered adding an overcharged version of Sonic's Spin Dash? (IE: Sonic Adventure: Sonic charges his spin attack and says "ready!" when fully charged.  Sonic can freely move around while the charge button is help down.  When released, he unleashes a powerful version of the spin attack which does decent damage and knockdown)
- Ex Roll Attack feels weird now that it doesn't knockdown anymore IMO.

Super Sonic:
- I agree with Divine regarding SSJ Sonics commands.  They do not feel natural to me.
- His Launcher is not listed correctly in the readme.
- His super in which he throws his opponent into the air and taunts confuses me.  What is supposed to happen after the super is performed?
- A unique stance and run anim would really set the mood for this Sonic.  He looks and feels just like Super Sonic.
- IMO, Super Sonic doesn't need the extra flickering FX.
- A few exclusive Super Sonic intros would be rad.
   - It would be cool if the Chaos Emeralds scattered after Super Sonic is defeated (Special outros if defeated by various enemies would be awesome too (IE: Chaos, etc.))

I'm definitely loving what I'm seeing.  IMO, this Sonic is almost perfect.
Keep it up bro.
