I get that some people don't lhe the shift in the perspective (just like some people hate female MC games), but I fully disagree.
The POV Switch shouldn't be just a "warning", it should indeed be a button, making that scenes optional for those who don't like it.
I've played a lot of Netorase games and a lot of them doesn't show much, like the wife only describe the things she's done without we seeing it at all. The parts where we "play" as Violet is a good way to show more of what she did and give a lot of more context of the plot.
Oh I really like the idea you gave about the perspectives being optional, it would've been a lot better experience to me.
Regarding your experiences with NTS games tho I feel like what you describes fits mostly NTR games, where if you choose male only POV everything the female MC does is secret and you end up lacking scenes, which I actually hate.
In this update specifically, with how the POV switch worked, it would've been amazing not to see what Vi did at the photoshoot, only knowing during the night. But I feel really afraid if the optional POV option is added we, who choose for non-Vi POV, would get less scenes and not known what Vi did at all ever, which would suuuuuck for a NTS teasing game like this.
I agree with your opinion about the POV switch button but it needs to be made right, not as you described as your past experiences in those games.
I did give some options for ways to know/see what Vi did without it just being a word of mouth from her lol, it wouldn't mean less scenes or locked content behind the POV options, but a different way to get the same scenes with the teasing aspect being empowered in it.
