Well, I finally found a copy of this at GameStop. It is pretty much the exact same game as the DS version. I love the DS version, so I decided to buy the Wii version as well.
There are four profile spots, so up to four players can have their own game. However, you can't name the profiles.
The game controls with just the wiimote. You point it at the screen and the shoot the balls with the A button. The B button is used to change the current ball. Controls work great and the game plays and looks good for what it is.
Honestly with nothing added over the DS version, the Wii version should be $30 or even $20 but there is no denying that it is a fun game to play.
