I also backed this project on kickstarter. My wife and I are playing the game together cooperatively even though it's pitched as being a solo game. She's been drawing and making decisions while I flip through the rules and figure out what our options are.

I came across two places where the rules point to "page X". I found the rules in question, so I'm only pointing this out to make sure the error doesn't slip into the print version.

We discovered a volcanic shaft right away and built a draw-bridge across it, but so far haven't had the chance to drop any enemies to a fiery demise. We've lost two of our dwarven soldiers in a fight against some golems, but are otherwise in good shape. It's a new style of game for us, but we're having fun!
