Hihi Zoey here~
Why not add thirst alongside hunger. (instead of grabbing two plates of food, why not one food and one water.)
Water for the crops to make them grow. (The crops would totally thank you for it ;))
And washing for hygiene and health? (Did someone mention plague/ diseases? I do belive so!)
Now I understand flowing water is difficult, so I’m not asking for that.
What I was thinking instead was to be able to dig a water well.
You could start out with a “brought along” supplie to get you started.
Then have workers/miners? dig the water well, and then have stone mason and carpenter
to finish the job.
