I tell you, being more expensive and keep on giving impression for players to pay up just to enjoy the game will give you 1-2 stars. I played the game years ago and it was more enjoyable than now. The upgrade pricing really depends on gems but you give less, very little ways to win gems, like leveling up used to give 7 gems now 6. And it is so damn rare to win anything let alone gems at the casino machine. And why did you remove the daily coin bonus from unlocked restaurants?
