The story doesn't have to get dark. As an artist, you can't plan and program everything in addition to rpiute or alternative routes. but it is not a must and the game has a lot of choices. But you could tell the artist that you think it hurt that Dylant rout depends on Aiden route. I have to say so exactly I can't all reout but I don't think that the two routes are star dependent on each other. I think you can get ahead with Dylan without taking the Aidan route. But I don't swear like guest there are lots of routes and choices where I don't want to say anything wrong. But in fact the story of the game can get dark if the path is chosen it is not a mustI recently started this game after hearing a lot. I loved it in the beginning. Really, I couldn't stop devouring the story, I like the slowburn and the renders are really good. Then everything railed off with Aiden's tasks. I can't imagine the fmc feeling some lust while being blackmailed by threatening of violence toward her family or find it sexy... And you can't say no without closing the door to Dylan's scenes.
And by the top of it, add the casino debt and mafia popping out of nowhere.
Why does the story had to turn dark suddenly? A normal housewife going down, little by little (the "slowburn") and then bam, very bad things happen and you don't have control anymore (even you as the player). It feel like a real weak plot as excuse to show "more" skin than before.
