In the beginning, it was a fun game, but whoever cannot pay does not progress quickly. The construction period is up to 34 days. It is a very long time, and there are survivors that you cannot get if you do not pay the real money after 7 months or more of playing. I am at level 23, but I am still Poor compared to people who pay money, the game is very unfair, and although we made suggestions, but there is no response, so my rating for the game has gone down, but i will continue for my friends 😊
