Guild of Dungeoneering

Grow adventurers by building challenging card-based dungeons

This is a really unique game; love the soundtrack. Sips (Yogscast) has done a great video on it:
A card game with all the benefits of a computer game. Simple and endearing style with humour thrown into the mix. Think of it as Munchkin Remix.
@cyhwuhx Love the pencil/paper art style!
