You can buy everything in the game - basically, it is a money-grabbing grindy experience. In-game items are overpriced and different for players - e.g a Home building costs 990 gems for my account and 500 gems for my friend. I created 2 support tickets to clarify that and both times got a copy-pasted template response about continuous development. Thus, user support does not exist. Don't waste your time on this game - there are many other better games on the market these days.
