GREAT GAME but it's a MAJOR money grab game. It sucks you in, let's you play and make mistakes the first couple of songs. And trust me, after the first couple you are HOOKED. It reminds me a lot of Guitar Hero. But after those couple of songs, you miss ONE beat, it shuts you down and asks for diamonds to continue. You, ignore that, it FORCES you to use diamonds to move on. Then after all your diamonds are spent, you guessed it, they're demanding money for you to continue. Uninstalling. Boo.
