Secondarily, no player should feel responsible for this game closing. DeNA is a terrible gaming community member and them letting this game and others die on the vine then shuttering them is their M.O.
It's too bad - prior to the Aug 2015 update, this was a fun game. And it had potential after the update but they just basically stopped doing much of anything. Then didn't "fix" the gem bug. Likely because they knew the game's soon ending lifecycle.
Thank you to everyone who contributed to this board. I really appreciated the information.
