Yes, I just found out about it from VGcats. So sue me. Either way, if you haven't, its an awsome game especially if you love Rhythm games and Elite Beat Agents.

Wow that's really ool. I'm downloading. And I notice they have Caramelldansen.

I remember trying it out a while ago, I didn't like it as much as the actual DS games though. It felt a bit too awkward with the mouse, although I'd definitely play it more if i had a tablet.

Trying it out now. Looks really fun.
