Great entry! Generally I don't like card systems (maybe I should, there's alot out there) but this one was well done and I actually enjoyed it. The movement and turning was all great. The dungeon was a bit bland and samey, so it could benefit from changing it up a bit.
I think if there was some expanding on the cards and fleshing it out a bit more it could be great. Like Captain Coder said - I'd be on the lookout for a full release! Overall a good crawler.
