A very fun rhythm game that anyone can pick up.
There isn't really a story, but the characters do dance in the backround. The main gameplay is easy to pick up on. You can use two wiimotes or one wiimote and one nunchuk. There are 6 cirles on the screen. Two red circles for the top, two yellow circles for the middle, and two green circles for the bottom. Small balls will float to each circle. When a ball lines up with the middle of a circle, you shake your remotes. When the balls go to the top, you point your controllers upwards and shake them. When the balls go to the middle, you point the controllers right at the screen and shake them. When the balls go to the bottom, you point the controllers down and shake them, and etc. Dance moves add to the fun too. A stick figure guy will appear on-screen sometimes and move his arms in a certain two circle area. You have to mimic him for a few seconds until he stops. There is a tutorial that explains it pretty well, so don't worry about getting it right away.
As you progress career mode(the main levels), you will gain extra sound effects and bonus movies. You start on easy and work your way up to super hard. The main reason this game wasn't rated better is because of difficulty. After normal, the circles come at different directions and stuff. Sometimes the controllers don't pick up movement when you want on hard and superhard, but after practice you figure out how to make it work better.
You can also just play regular songs for fun or play different minigames, so don't let difficulty push you away.
Overall, this is a creative, enjoyable party game that anyone could have fun with. Feel the beat, shake your hands, and enjoy!
