Absolutely amazing, somehow more impressive and cooler than the modern sonic mod, the attention to detail is unreal, the light speed attack is just as if not cooler than it is in Adventure 2 Battle, and way more functional this time, not to mention the super form playing EXACTLY the same as SA2 and by extension it's "go super anywhere" mod, even down to being able to switch between flying like in the Bio Hazard fight and running like normal gameplay.
