A fun little time waster.
You probably wont want to play this game for more the 20mins at a time, it can be painful on the arms if you are not used to the movements but you do get used to it. There are a good selection of songs available to choose from and you can also purchase more if you would like to.
I gave this game 7/10 because it can get repetitive after a while, it is good if you want to waste 20-30 minutes but after that you probably wont touch it again for a while. Overall the music, the graphics and the gameplay are pretty good and i imagine you can pick this game up pretty cheap these days, so if you see it cheap, pick it up and give yourself an arm workout!
