I played it like a game. I wouldn't spend any money, AND, I would see what happened when I had accumulated 9,999,999 coins and then got just one more. Would I crash the database?
Got to 9,999,999 last night, got one more ... and nothing happened. So I sold my bees, cat, and chinchilla (saying goodbye to the virtual beasts), harvested the last crops, and deleted the app.
More time to do important things, like watching Torchwood :)
