After careful consideration of feedback over the last update, we have implemented some changes that should help all round with resources.
We have reduced the heal costs across the board.
Resource Tiles have been drastically improved. There are now more silver ones spawning, and all Resource Tiles that spawn from now on will have more resources available on them!
So as soon as the current resource tiles are used up, you’ll see a massive jump in the amount of resources on each.
If you want the official link here it is.
