That's a fair point and something I will address in v0.8.3, I'm going to seperate each character (as much as the story allows). I promised on my Patreon page that you can "choose which girl you want to pursue" and still intend to do that.
That being said, of course there are some storylines that are strongly tied together and will remain.
I find it odd, not necessarily a flaw, maybe a problem in presentation, I can understand if you want each character to be interconnected, it makes sense, one person know another and so on, is the interface that betrayed me even though the phone does say to first progress with X character.
Well since you are in this thread then I can also say thanks for making it, I have enjoyed it very much and even if it took me a while to get it, I am glad the games has systems in place to let you know just how far you can go with a character and where you are standing.
My only complaint might be how renders lights might be a bit flat compared to other games, but is not even something that happens everytime, I am quite fond of the Veronica's renderings in the Sauna for instance, speaking of wetness, looking forward to more bath or shower scenes, maybe you could set it at around sunset, but oh well, whatever works for you should be good.
