Amazingly well made.
Well I shall be truthful, I for one have been one of the strict followers of Shadow only being able to go "Hyper" as he is supposedly the "ultimate lifeform" Giving him the natural ability but, this works extremely well. And with the unification via Chaos Control, bending time and space, via the ending I'm guessing only a sustained "Hyper" Transformation could allow such a trick to work. Personally I think it could work truely in the sonic universe. But that's probally just me, overall I'd like to see SEGA/Sonic Team pay you some money...Could make an amazing game...Better than what they've brought out at the moment...(Sonic Riders for a good example).
