I'd like to add my vote to those asking for the arrow keys to work. Mouse-only is a minor nuisance, but builds up in the course of play.
On the village, when I looked at the beta before buying I was kind of looking forward to starting with a blank clearing and slowly adding and improving buildings until you got something that looked really cool (and potentially different from your friends' villages). As it is, the village looks the same no matter what you work on. Is there any possibility that something like this is in the pipeline?
I agree with those who want as few hints as possible about what expanding a race or class will do for you. I like surprises.
The dungeon that forces you to play as a gnome opened for me before I'd upgraded the gnome "house" to Level 1, although it seems to have vanished for the time being once I've surrendered in it (still haven't upgraded gnome). I'm not sure whether this is a bug or not.
