I really liked Amber — the story developed very well — but I felt there was an issue after some of the choices, especially when she tries to get back together with him. That time when she invites him to the swing house, I think it would be interesting to have the option to go with her, and there he could see a different side of her and end up liking her that way. Maybe they could even stay together in that distorted kind of relationship instead of having only two ending options. Perhaps that could be a third ending, and honestly a more coherent one. So I think there should be one final opportunity for the character to make that decision.
But overall, you did an excellent job here. I believe there’s definitely room to continue and improve it even further.
