Yo Denki,
I have an idea: It would be cool if the folks didn't just sit there, like Mabye if you feed them and they are happy they could help out or something like that. Mabye if after a while they get hungry they would go back to there hut and request food. (Maybe the thing they could do is if you build a big fenced area with a gate they would once happy go in and maybe doing things with other folk such as playing a game. Or they could help you build.) Another idea is maybe sometimes the folk would go inside and look through a window in house and then when hungry come out. It's just an idea, sorry if a worded it weirdly.
Great, great game so far!! :)
