A little too frustrating honestly to enjoy. When hoping that these little guys will do the right thing I would often find that a lot of them died due to famine. Most of the time it was because they'd be walking towards some wheat and then turn around before grabbing it. As well I noticed that the Circle would appear most often when units in combat were reaching low life which makes sense; gotta keep those guys alive. When I chose to attack though they just bundle on top of the baddie then get hit before making their move. Shouldn't they attack first, especially other ones rallying to attack?
Overall it's a tough challenge. There's just too much lack of control to be considered really fun in my opinion
