I have the game, it's pretty fun. I enjoyed it but got stuck on the 8th level on friday, tried it again on sunday but failed again. Haven't been back to it yet because i'm in the middle of a play through of Zelda OOT and want to get it finished.
It is a pretty good game though. Theres a review http://www.wiiware-world.com/reviews/2009/02/onslaught here for people wanting to know a bit more.
