I love the game. I hope see an Android version!
Maybe requires only fix the price of some cards and change someones, because are useless.
*ANVIL: don't must increase cost of card. Back this card ''anvil'' useless. In this case, this card must be an event that modify the deck.
*Dynamite: must be cheaper, to destroy started cards.
*Hammer: more cheaper, too. Only increases cost if you use more times in same round. For next round, again, 3 ore cost. This you must be patient to increase slowly round by round and not spend all ore inmediately...
Add cards that need discard cards to use, like the mechanic of ''Nemesis board game''.
GOOD GAME! Continue improve it please. A big hug developers! :)
