Excellent mod! Charmy and Mighty play exactly how you'd expect them to, Espio, Heavy, and Bomb had appreciably unique aspects added to them to make them more unique and SRB2-ish, and Vector's entire moveset is really original and kicks ass. Perfected amounts of polish everywhere...
... uh, except on Mighty. No idea why his wall cling and hammer drop are mapped to the same button. This led to a lot of unnecessary headaches when traversing pretty much anything that involved being near a ledge.
That doesn't take away from the rest of the pack being good, though. Great work!
EDIT: Forgot to mention - Mighty's super form is a no-brainer, and Espio and Vector make /some/ sense (Sonic and Knuckles analogues), but why do Charmy and especially Heavy and Bomb have super forms? o_o
