I got to day 15. It's annoying though, I can't seem to figure out how to expand safely. No matter how many outer walls I build or how many soldiers I hire they always seem to end up broken and slaughtered, and the enemy is only repelled at the keep. Then the more stuff I had before, the more money ends up getting wasted. I think a lot of it is to do with the way my guys just wander around aimlessly, not having a way to direct them to more useful and/or safe locations is really irritating.
