I play this game so many times and for so long. It's really a good game. But, it's kinda boring. You dev, need really to change your system in the game.
First, I have a million of silver coin, but it useless !.. come on man. What are you thinking?!.. I only spent those in every play only for voucher point or whatever it's name. And I achieve another silver coin by achievements. I can't spend for buy prime skin, weapon skin, or something physically. But you make it every physical aspect must be upgraded or gained by points?! What logic is that?!
Are you really out of ideas ?
What is the purpose of my silver coin now? It can't be used for something.
Dev, you can't just rely on graphic, you know
