Was a Great game
But the developer is doing his best to destroy it. Zero customer service, zero consideration for the feedback of the users, repeated need of maintenance with server downtime, rules changed continuously; these are just a few of the negative observations. For a complete picture just read the dedicated pages on Facebook. Last modifications have been intentionally done only to worsen the playing experience and to force players to spend more and more $$$.
Really over any reasonable limit.
I am already started seeing many players quitting the game.
At the end, my personal suggest is to play another game!
