Good but buggy

I like the game but can not recommend you buy it until they get bugs out. I am running a brand new 27” iMac on Yosemite and the game will freeze up and the only way you can get out of it is to turn off the computer. If you do an inApp purchase for no limit on budget and unlock all building materials it unlocks for instance pythons or cement but will not let you use it. This game has tremendous potential for all ages but please, please debug it. I bought the complete game by the way.
