Great, but nothing new
It's a great remix, and it really brings me back to the good ol' days. Still, this is much too overused: A slightly techno-ish remix of Green Hill Zone. Practically every remix I've heard on Newgrounds is the same beat, same theme, etc. Nevertheless, it realy is a fantastic remix that I'm sure any Sonic fan would love. But again, it's really just the same-old same-old. 8/10
