I've spent a good part of the weekend playing, and the game is strong. There are real consequences and ability to take chances that give it an edge over more linear FPS games. Combat is already quite solid, the trap rooms are a nice difficult challenge, and the bosses are fun. The unlocking of new characters is a nice touch as well. Overall a great mix of roguelike and fantasy FPS.
