This game is INCREDIBLE. I just bought it for Steam and it is so addicting. If you like music games and shooting stuff, this is your game. It’s like Geometry Wars on ecstasy. The visuals are outstanding. There are a few UI things that bug me, like the file browser for personal music. But the gameplay is so fun I can ignore it until an update fixes it. 

Buy this game or get the demo, you won’t be disappointed. It’s also available on Xbox live Arcade but it doesn’t seem as polished as the PC version.  360 controller is a must for PC version, otherwise it’s harder and not as fun.
