The idea is great and and i want to see it even bigger. Had trouble with the camera as well, having to use the top of the screen to readjust my position on it.
Since you had the money cheat i went with home turf to single out one and make him grow as much as i could, he was eating all my money but i guess i was feeding someone 3 to 4 times the sizes of a normal guy, so he was eating me out of business, the poor guy, really need to had bigger portions or a hose to help these starving customers.
I also assume the last 2 areas are greyed out but arent unlockable as i cheated a lot of the money and they still didnt appear. Hope you can develop more for this in the future.
