Hi there, I apologize for the late reply.
Choices with consequences are all clearly marked when you stumble upon them. You won't be able to miss them. To add a bit of information:
Dark includes darker events happening to girls around you as the MC slowly becomes more selfish and corrupted. Kinks include BDSM, gangbangs, and avoidable NTR (sharing them with other men with or without your consent)
Good includes more positive events, with more focus on harem-building and love. Kinks include impregnation, mild and wild kinky sex, and becoming a father.
This game is quite large and is made to get more interesting over time so do not expect everything to happen within the first couple of hours. Have fun!
