What a terrible game, at least at the moment. Completely unbalanced and unplayable, looks like an alpha demo. Can't believe what they are charging for it.
Well,. at first it seems very unbalanced, and it's very grindy, but, when you loose you get money and metal, then you upgrade stuff from main menu, then game become easier and very interesting to play. After hour or two is piss easy.
