This is a sick yet awesome game. And I got all the badges! Follow the 10 step guide that's been floating around the comments and it'll be a breeze to get all the badges.
I find it weird that I can beat SCGMD3 and not SCGMD2. The songs I'm stuck on are far from more difficult than the songs in SCGMD3. The only problem is the lag. And no one here can blame my computer because SCGMD3 works just fine. It's this game!
