This game has a very interesting concept. At $15 I think it's a steal.
A light card-based dungeon-crawler that puts you in the shoes of a dungeon master instead of the adventurer himself. When exploring, you decide the dungeon’s layout by placing rooms, enemies or loot, then the adventurer will move on his own.

Does look fun though.
