Overall good approach. Some hints: Achivements don't vanish by themselfs...clicking them should not be neccessary. And I build a farmer joe and got the achivement: 50 buildings unlocked....Joe is a building?
Thanks for the feedback! I agree that clicking close on achievements should not be necessary, and this will be addressed in the next update. Buildings are just anything that will generate more crops per second, perhaps it may be better to change the terminology for clarity since many of the 'buildings' you buy aren't really a building by definition.
