Nice game! An issue that can be fixed is that when you click to unlock a new item/material and you click fast again to select that material, it buys you the next one instead. Happened to me and its kind of annoying. 5/5 anyway!
This is the best Card game on Kongregate right now, you really don't need to pay to enjoy the game at its best. I'm hooked with the campaign so I didn't try Multiplayer yet, but I have high hopes of it. 5/5 an example for card game developers. And this score is without mentioning the terrific graphics it has. Perfectly crafted. 10/5
