As a hardcore fan of both fap VNs and Dark, this is great.
Once I saw where the game was headed, I considered restarting and renaming myself Jonas Kahnwald just to see if you had put some Easter eggs in, a yellow jacket, maybe.
I am hoping that the MC will end up outdoing Bartosz and be ground zero of pretty much everyone in town, Scarlett being the first of many. Maybe he can outdo Charlotte and become his own father. Maybe his own grandfather, too.
I didn't look to closely at the layout of the rooms in your story, but that is just one of many possibilities for Easter eggs that won't break copyright laws. A mobile home by a truck stop, lots of rain and no umbrellas, a watchmaker's shop...
I am very much looking forward to seeing how this all progresses. Keep it up, Jestur :)
