Played the game and reached the end so far and there is only a little something in mind.
I didn't bother reading the 60+ pages so maybe it has been asked and answered or discussed already.
Could Emma (Carola's daughter) be MC's daughter somehow ?
MC began his killing spree 7 years ago, MC recognized Carola as a girl he stabbed 7 years ago, and thought she's been dead.
It is never said (If i remember right) MC raped Carola at the time, but when she says "I have a daughter. She is 7" my mind was like : Oh really... ...
As for the game, I enjoyed it. Im used to play more "gentle" adult games and wanted to test something more hardcore and the game delivered. Good job to the maker.
I first played with only "red answers" and then did a quick rerun with "white answers" to see if MC was more gentle (especially to his mom) but he was not that much, there is still violence to the mom and all. I guess that's just who he is.
