I loved this game on the XBOX 360, so how does the Wii version fair?.... Well in a word its brilliant, loads of new shapes with new characteristics, the 'Wii mote' and 'Nunchuk' are a perfect addition.
I read in a review the game suffers slow down!, there is none believe me I have been in some frentic levels and this is not the case, the DS version on the other-hand has plenty of slow down though unfortunately.
It is everybit as fast paced as Retro Evolved (which is also included, and can be sent via wifi to 'Download Play' on your DS without the need of the DS version).
The only reason I gave it 4 out of 5 is because one niggle the save file cannot be transfered to the SD memory card for backup it will not allow copies of the save file to be made.
If you get the DS version u can unlock an extra planet by wifi link between the two games although there is enough to see and do without this.
This is a fast paced pick up and play game with a 2 player option, that is very addictive, and you get a drone with various abilities to accompany you, which levels up with new power-ups (ranging from a shield to a turret ect...).
At 17.99 what are you waiting for? play.com are right on the nose here at this price point.
