This is curently one of the games that i spend my time on and probably will do for a while untill the PC version is released of it. The game have a nice cartooney feeling over it and it's a must have for tower defense lovers aswell as the RPG maniac. The game runs smoth on my iPhone 4 atleast and will run perfect on an iPad. Personally I really enjoy it and will defently play it alot more when i get the spare time for it.
