Great game- very addictive and lots of levels to keep you going. To people that complain about the controls, go to Trackpad Settings in System Preferences and enable the "Three Finger Swipe to Drag" gesture. Then you just have to swipe accross with three-fingers, making it more iOS-like.
One thing stopping it from 5-Stars: Theres iCloud Sync for Game Progress on the iOS Versions, which I love because I never have to repeat levels. Id love for this to make its way to the Mac, which shouldnt be too hard to implement now that iCloud is integrated in OS X.
UPDATE: Mountain Lion is out now, adn Game Center support has been added, but still no iCloud Sync. This is very disappointing because I love the game, but I have no intention of spending hours replaying levels Ive already completed on my iOS devices. I cant imagine this would be too hard to incorporate, as its already there between iOS devices.
If the game wasnt as good as it is, Id have brought this down another star.
