Porn Game: Heritage - Version 0.4.2 + HotFix by GeppettoPossum Win/Mac/Linux/Android

After the festivities of you and your twin sister Emma's 18th birthday party, your mother sits you all down and reads you an important letter from your late father. The contents of the letter will forever alter your family dynamic. You learn that you have a...unique Heritage™ (heh). Be warned, though, as others might be out to capitalize on it.

Spoiler: More Details
I first became interested in these types of games after stumbling across F95 a couple of years ago. As a gesture of goodwill, I will be posting this first release on here. For future releases, obviously I can't control if they get leaked ;). If that happens, I'll update the links here. If you enjoy this first release, please consider supporting me on SubscribeStar.
Constructive feedback is appreciated. :)
This will be primarily an incest harem game. Due to circumstances explained in this first release, the characters are already sort of "primed" for each other. As such, there probably won't be a ton of "will they/won't they." I'm not ruling out some teasing and/or prevaricating, but it won't be as slow of a burn as some other games in this genre.
Please make sure to check the tags/genre section to see what I have planned and decide if this is a game you want to try. Where applicable, I will list which fetishes will be optional. At this point, the list is not exhaustive and I'm sure more will be added down the line.
