Super enjoyable.... until you play 20 minutes into it. It goes from easy to extremely difficult quickly. The only way to advance is to upgrade (medical equipment, doctors, staff). To do that you need coins. To get coins you have to beat the levels. To beat the levels you need to upgrade bla bla bla. There's no way you can expect players to win this way without another option of moving forward. Fun game. I'll come back to it when the game itself has been upgraded. Until then, delete.
