Not really going to bother commenting the rest of the game, just this one thing:
Are you sure you know how incest works? The whole taboo nobody can talk or think about?
Yet, one of the first scenes shows the MCs mother's thoughts, how she sociopathically lusts for her son and wants to send him nude pics of herself. And before you know, she is sending nudes of the MCs sister who is obviously in a lesbian relationship.
That's just... double *yuck* for the sister, lesbian NTR?
And with the mother already having the hots for her son before we even get to act, well...
This is like "Le Caramboulage" of writing. Pouf, badadoum, le whole tabou is going down le closette before we even got started.
