This one took me a bit by surprise, having received it as a gift for Christmas. After a huge dose of WTF is going on right at the start, it wasn't long before I got into the swing of taking another "step" onto a card and hoping it would be something good.
Adventuring takes place on encounter cards.
Yes, exploration is done by flipping over cards and successfully completing encounters unlocks more cards which I found to be a neat way of having mini stories. These encounters are not necessarily combat, which plays much like the Batman: Arkham Asylum series except you're not Batman and the fights quickly go from being super easy to requiring some gamer skill.
The main goal is to beat each member of the courts of various suits: Dust (bandits), Plague (ratmen), Skulls (skelies), and Scales (lizardmen) and finally the very well voice acted Dealer who acts as the antagonist in the game.
Pretty cool for a Unity made game!
My favorite parts about it are you can customize your adventure deck with cards you have unlocked, tailoring what you can and what you won't run into on a quest - or have everything included in Endless mode. The way it is structure also allows you to progress despite dying/losing a game which is great design. Also, the final fight is very cool. Make sure you get to it. :)
This is definitely one I can recommend, and give it 4.5 minotaur tracks out of 5.
