Small spoilers!
I think you misunderstood me. I mean there are already messages at *Talk* options in which the game indicates that another caharacter's storyline has to move on before the next event of this character became available (like higher friendship with Lin, or a higher obedience from Andriod for example). In my opinion, there are more points in the story when this "restriction" is needed.
Ok, it's not a classic sandbox, but the player has the freedom to decide the order of events between characters, which is good, but I think it would be better, if we can't run forward with one or two characters, because - for example - we don't have the money what we need for another. And I understand if somebody doesn't want these restrictions, because those are make the game more linear, that's becauzse i suggested to make it optional.
My examples aren't serious problems, but it gives me a feeling when I'm reading a book, put it down, and when I'm picking up again, opening it a few pages later, and after I realize what happened, going back and read the missing pages. It's not the end of the world, but it's ruining the mood among other small things. It's a little bit funny when Maria says that she gave me 1 blowjob, and I never licked her pussy. Duh

Or when Maria says that you should keep distance from her, and you have sex with him when she playing with Lin (or the Android, I don't remember).
Anyway, thanks for the answer, and I want to say I really love this game, keep it going, and it's more important that you have a good mechanic, characters and fantastic story like these small imperfections, so let it go, if you don't agree with me
