I got this game as a present from my boyfriend one day, and I thought I would just try it for a short while since I had other things to do. But it turned out it was a hard game to put down. It is just very good! The rhythm games and catchy and the animations on some of them are just hilarious. It is just a really great game!
The only "bad" thing about it is that the rhythms stick in your head. Or at least it did in mine. It was a bit hard to fall asleep a few days because I was lying thinking "tok tok tok tok tok tokotok" and others :)
