How is everyone else liking the demo?
After restarting a few times, it appears the best way to keep your economy going is to make bread and sell it. Even a small field can support a shitload of bread production with one windmill and a few ovens. It produces more than enough bread for you to sell for a high price via the trader building, and then buy other goods. That way, everyone can get goats and chickens in their backyards, and the food problems are alleviated even further.
