I like playing this game... buuttt I reakon a few things need tweaking. Like the coins you get and trying to upgrade personnel and equipments doesn't work out at all. U have customers on 9 difficulty and staff on 7 but u cant upgrade cause u cant gain the coins.. maybe to help this you should be able to go back to previous levels and try and get the star and the extra key for the box? Also maybe have a 2nd nurse on the floor can help?? Just some thoughts..
