Edit: Pretty obvious from the response the developers don't care about customer satisfaction. They only care about making you spend actual money. Game deleted. I was really enjoying this game, but they have clearly just changed the amount of coins you get. Where you used to get 250 odd if you earnt 300 but lost the level, now you only get 25. This makes it impossible to pass levels without paying actual money (as upgrades to your clinic cost 500 coins or more). It's now impossible to win without paying actual money. Shame - I really enjoyed this game.
