I've deleted this game because I kept losing gems because it's too easy to accidentally spend them on things I don't want. If it was as elf nests that would be okay. But it asks me if I'm sure about that. But when I accidentally hit the button that adds stones, it doesn't ask, it just buys the stones. It's easy to get more stones. I don't need them and I don't want to waste gems on them. So now I'll have time to do other things.
