Not wanting to defend the DEV or anything, but I think the problem must be in translation even, because playing in the original language (Portuguese), the dialogs are well for me, I would even say "very good". I've seen some games considered "good" with much worse dialogues, which can also be caused by the translation into Portuguese.
Do things seem to be going a little fast? maybe, we don't know what the DEV intends to tell here, so maybe we're still scratching the surface, who knows.
CirclesC I have the same doubt as
Ara-sH, what kind of incest here if it's not a big spoiler of course. And someone from the MC's family or among relatives who are not part of the MC family?
Other than that, good luck with your game and rooting for it to become something big here.
