Yeah I dunno man, this seems like a deeply specific fetish game made just for the creator.
- It's an incest kinetic novel about a black family right?
Except the black women all have weird bright blue eyes and the "protagonist" doesn't look related to them at all.
- It's a NTR game right?
Except the protagonist doesn't know about the sexual harassment happening to 2/3rds of his family, and in the situation with the last 1/3rd the "cucker" helps him have sex with his sister for the first time.
- It's a dark game wherein you corrupt and deviously break the wills of your family/harem like Blackheart's games right?
Nah it's just a rape game. The protagonist isn't clever or anything, he's a psycho that's a slave to his urges and he basically gets caught raping his family a couple of times and the plot just bails him out. He only gets manipulative in the most recent update because the sister presents the opportunity to him on a silver platter.
Speaking of the sister, she kinda highlights an issue/weird bit of this game which is that usually with dark plots like these that contain and focus on non-consent usually either make the targets downright unlikable or focus on the protagonist and his machinations. This game very strangely puts a focus on the trauma of the victims and *tries* to have them react in somewhat realistic ways which just makes the majority of their story deeply uncomfortable to read.
Like I said, a really weird game with some niche ass subject matter.
