Cool game! +1 on the wishlist :)
I don't play optimization games (is that the correct genre name?) like this often & thought after the first few expansion (the caves especially) that there is a world simulator hidden in this tavern sim :D But i got the hang of it pretty fast and had a lot of fun with the different traps and monsters. The progession & difficulty curve is pretty good.
The game also looks very nice and i enjoyed the sound design.
I'm looking forward to where it is heading!
