You have a strong and unique battle mechanic with the devour, but I spent a lot of time wandering around, not entirely sure what I was meant to be doing. I think (based on previous comments) that you're already aware that you could definitely use a little more guidance for the player. I thought your outdoor maps / cave maps were pretty nice, but the interior / house mapping was a little empty and plain.
Overall a solid entry; good luck with IGMC! :)
