I think that a way to organize the family tree visually would be less confusing. It could also be added in a different section, like the babies section, because editing each sinner's relationship separately can be a bit tedious
the relationships are a bit buggy. I tried to make a sinner the father of other sinner, but when I went to my village he appeared as her son instead of her father. Also I tried making two sinners siblings but when I went to my village they appeared as not related
feed them their favorite food or hide and unhide them with the flip-phone (this resets their mood and gives them full faith again, this also resets their favorite foods tho)
