Started this today. For a hack and slash I like it. I agree with MTK though it does get repetitive and that first stage boss battle was pretty bad ass. Some of Zed's phrase has me dying "Vanilla Slut!!!"
It's short as hell though. I already finished it and i'm going back through for coins and shit. it's a different game when you go back through because you have so many more combos, and you can concentrate on 'sparkle hunting'
