Not sure if you remember the old achievements you could unlock on Google Play Games, but gathering experience was really fun. I wished we could have that back. Also, they could be reachable for Facebook account as well, I believe. Any chance? And I needed a proper clarification here... Why exactly did the developers remove it?

Ohhh i understand now! Unfortunatly due to some changes happening with King games, the devolopers are maybe getting rid of the Achievements feature and remove it from Kingdom Accounts! But no worries, they will bring them back in the future probably release them as a Google Play Games Achievements! Who knowns? Hope that helps... See you around!
