Developers got greedy
They listened to some of the reviews, but the update was clearly meant to make the developers more money, and not to make the game more fun. You can see it because all new items cost a lot of gems instead of coins and old items cost even more gems (the robot is now 1K instead of 700), it costs more gems to recover trades, and the rewards give you fewer gems than before (5 instead of 25). Note: I think they changed it back. It would take weeks to make enough gems to buy anything, and thats considering you dont use them to recover trades.
Another problem is that there is no leaderboard or multiplayer aspect of any kind, so once you make a few billion and buy all the furniture, the game becomes stale. They should have a better end game.
