Knack $29.99 at Amazon

Still $10 too much...

I guess they're price matching Groupon.  

I got this for $25 from Newegg a short while ago.  I needed a game to play until Watch_Dogs came out.  I must say I am enjoying it.  Its a game you cant take too seriously.  A mindless kind of fun game you can play for a bit and put down.  I should have it beaten by the time Watch_Dogs or MK8 comes out and I can probably get what I paid back in Gamestop credit for trading it in towards them after bonuses.  If you're looking for something fun for a month until some good games come out, I recommend it.

Is this game similar to Kameo which was a launch title for the 360?

its a solid (and good looking) old school platformer. solid lenth as well. i have to rent this out from gamestop to finish it
