Card Crawl is a solitaire style Dungeon Crawler played with a modified deck of standard cards. Clear the Dungeon of 54 cards by using item-cards, slaying monsters and managing your limited inventory. Each run you can use 5 ability-cards (mini deck building) which will give you unique skills. By collecting gold you can unlock 10 ability-cards in the basic game, or up to 40 in the full game, which enable new tactics and even better highscores. Source: The Publisher Website.
