Yes I’m one of those people who are playing this popular game.
I just play it quite a bit especially when I am bored and nothing in particular to do. I am am not like the rest who are decisively more into it. I have been hearing complains from wives who are very pissed, aggravated and sad to see their husbands’ face glued to their phones and parents to their students who skip reviewing the lessons and purchased gems for occasional upgrade. I know, it’s annoying!
