Looks awesome so far. The only thing I might tweak is the mini map. I got lost a few times when looking to use the level in a scene but I can see why you did it. Players having a mini map and being able to scroll all over the map really bugs me.
I play on doing something with the big open farm in my campaign. Possible huge goblin raid or Diablo like demon invasion and you have to clear to the opening ( the rock pile in one corner) and go in to destroy the den of evil.
I did open the level with all the creature and turn off peace mode and unpaused the game just to see what would happen.
Glad you found a good use for my farm area.

I am thinking about making the minimap available in a later version. Getting lost does suck.
