I'm pretty sure the reworked prologue is at least partially due to the complaints about the NTR vibe that was present by default in the original. A lot of people regularly complained about Alexia warming up to her captor so suddenly. Narratively it made sense as she was isolated for months with only Andras showing her attention and kindness. However, to the players it could seem jarring because from our perspective she was captured only a few minutes ago. So I think the change was to change to perspective that this was primarily an NTR game.
Personally I do like that the new intro puts the agency into Alexia's hands rather than it being Rowan's decision. However I do miss the scene of Rowan confessing that he had serviced a twin and telling her that the same will most likely be expected of her as well. I don't think it necessarily has to lead to a sex scene, but I think the sudden realization on Alexia's part that she might not get a say in the matter can be a powerful moment. So far Andras has respected her wishes, but at any point he could just take what he wanted and there would be nothing she could do about it. This realization could leave her feeling fearful or aroused, or maybe a bit of both.
Speaking of extra art for the game is there any place i can see the extra commission art for the game ?
Sorry I wouldn't know, I think they were private commissions so it would have been up to the commissioner up upload it. I've just seen people posting pictures in this forum asking how to get that certain scene, only to be told what I mentioned above.
