This game feature rapes; it was kicked out long ago.doubt somethin incest related happned because ryen woud be kicked form patreon (site) because patreon term of service and everthing with questionable contet get removed.
I dont thing Ryen woud risk that, you can implie that but no real acttion.
(and dont foregt about those who usptet by something like incest- oh boy that coud start an outrcy)
Actually there's already an incest scene between two sister as well a mother-daughter threesome which you could argue is also incest.
That being said I'd appreciate if we do not end fucking our daughters
