Well I still hope the Steam release will have proper incest. Either that or get a proper incest patch. Even with the lewdpatcher I've noticed some inconsistencies. For example, your classmate Macy? I think her name is calls Linda your Landlady and says she wasnts a deposit from you for rent. Also the MC says he's known Caroline for years and met her at school when they were younger early on in the game, It's been awhile since I played this so I don't remember if that was in the original. It's pretty clear the relationships are meant to be incest based on many of the interactions and things being so awkward or taboo between them it'd be nice if all the dialogue reflected that without these inconsistencies.
And I really hope the Steam release will have the proper Celia path, the true version of blackmailing too.
