The fact that it's free and they're subtly spreading a message that is worthy of the cause, speaks volumes beyond simply trying to draw attention to themselves in an attempt to profit from it. They took the high road, and I commend them for that. A clever message, crafted by an already established and well recieved dev team, making a point about not only conserving, but being philanthropic in their approach....that's high art right there folks. A rare bird in a world of herds.
Beautiful, clever, fantastic. free!! What a wonderful game. I second exactly what everyone else has said in the thread. Love this..
Amazing! Totally down with this being free and created by energy company... Personally I'd say instead of asking to build more levels with IAP we can instead state build more because we like it and it can bring their message to more people! Thanks for making it and keeping it free.
