I think there is a bug. Are you supposed to be able to click on the deck to search for a card? I can just give myself 4 a bunch of mines on turn 1 and just wait out the rest of the game to win every time.
Great job with this. I’d love to see it developed to have a bit more of a strategy. I think giving cards a price to purchase would make this much more interesting. Right now, it seems the best strategy is to skip factories and just go for mines.
