I've been playing this game for a year and a bit now, and it has been fun most of the time, but less and less. It somehow lost my interest, because of the adding of more things and items to progress.
In general i think Too much Tapping for too little fun, and above all too much spending to progress ruined the game for me.
Now with the latest $in eyes, it's done for me.
I wish you all the luck, (I don't know how to say that in Chinese ) and admit you done a freaking great job, exploiting the human nature at it's best. I Dare you don't have the guts to issue another 30day shield or have a poll to ask if one would recommend this game to a friend, you'de be surprised I think of the outcome.
