As awesome as this is, there's a few problems with this character:
1. The Insanity Mode can be activated in Special Stages
2. Sonic has no transformation sprites and just stands there, I suggest fixing that, as well as some bugs that come with being Super (despite not normally being accessible, maybe give him a new Super Colour)
3. The new Black Core Zone Act 2 boss still uses explosions, as if he was still robotic, I suggest maybe replacing the explosion graphics with electricity.
