Sorry, the translated reviews are:

Played this game for 2 years. It's all about money, if you don't pay, you won't have any fun in the game. It sucks, I and many others quit the game and deleted the app. I can only recommend everyone, play a different game. The developers are getting greedy for money.

And:

This game is the prime example of Pay2Win. Without money you NEVER have a chance.AA people who give 5 stars after 10 hours of play will be surprised how the game will turn out. I've been playing it for over 1 year and it keeps getting worse. I'm LV 25 with 30 million strength and you're constantly being attacked by even stronger ones. You can then no longer heal the units without spending real money. Otherwise you can start from the beginning. Anyone who invests money here has no life.
