Be careful about dowloading this game if you are still using Snow Leopard

The in-app purchases will not work in Snow Leopard. OSX 10.7 or newer is required.

On older (2010 and older) Macs using 10.6 or older OSX, the game is a memory hog. You will have to drop other applications while in it. If I ever get Apple to finally send me the download link to Mountain Lion, I will upgrade and then be back in business. (Not yet ready for Maveric)
