Thank you so much for playing and your feedback.
The barracks and churches are actually a way to create stronger units. You can send men/woman into the barracks to create puncher/archer. The church turns women into healers. If you want to automate this, you can select a house (or a group of houses) and right-click on any barracks. Those houses will send newly created men/women to the closest barracks (no matter which you targeted).
I really need to add some kind of tutorial :P but it's a question of where to put my focus. Lot's to do still...
