2) No NTR.Looks like there are many questions.
Here are some answers:
1) Don’t mind the names of variables. Consider alpha/beta as just the way you build your character. More rude or polite etc. It doesn't necessarily mean you'll be beta for girls. With high enough alpha score you'll have options to be more pushy and aggressive. But with high enough beta score you could act more romantic and gentle. Some girls will like more alpha MC, some more beta MC. For example in intro if you have high enough alpha score, Olga can let you touch her boobs.
2) No NTR.
3) Mom is not a romancable character.
4) I'm not sure about harem yet. Most likely not. My main plot outline is ready, and I don't think it fits to the story. But I can say that I'm still thinking about one of the endings where MC will be able to stay with more than just one girl. Not a 3+ harem happy ending, but still something.
Maybe I get this tag wrong. But why would you think if there's no harem tag, you'll have to watch other guys fucking the girls in the game?) All girls are yours. Just not all of them would like to be in relationship with MC and other girls.
6) Interracial means "Sex act between 2 or more people of different races." Correct me if I'm wrong, but sex with Asian is also interracial. Anyways I plan to add a black girl later.
7) I want to emphasize again that femdom is optional as well as any other "specific" fetishes that will be added later. Even if you resist Octavia, and she's acting more dominant.
3) Mom is not a romancable character. SIGN ME UP sorry for doubting you just read your post.
