There was a new update where the developers took away a bunch of ways that the players collected resources in order to make the game way way way more grindy. None of the packages you can buy are worth the small amount of resources they sell you. You will hit the pay wall quickly and it'll take forever to climb that wall with these new changes without dumping hundreds and hundreds of dollars. A solid game to play for an hour or two albeit repetitive. After that, uninstall and do something else.
