Fun until it's impossible, once you get to the new hospital it is practically impossible to advance without spending a lot of real world money. You'll make about 200-300 coins per lvl while already dealing with the high pricing of the previous hospital and the lvls increasing in difficulty with every one you pass. You're back to square one, making infinitely less, yet spending more. Had to delete since I don't want to spend money on it but the lvl I hit isn't possible to pass without doing so
