This game -REALLY- needs better markers for when routes are opened and ESPECIALLY closed for different choices. especially given how restricted and bad the save system is, as well as unpredictable times when those restricting decisions pop up. I went through sooo many gameplay hours after already accepting the police officer's request(also not knowing whether or not that entire route would be completely deleted and unavailable to me if i declined), not even knowing that I wouldn't be able to ever seduce Katarina forever after simply talking to her once or twice, practically permanently ruining my progress for literally no reason. It also doesn't help that there's no rewind function or ability to undo or make impermanent these kinds of mistakes or restricting decisions, for instance my first playthrough I declined the coffee barista's advance thinking that "barista's route" would cancel out romance with Anna, but it just ended up ruining my save because no matter how much more I interacted with her I would never be able to do anything with her at all, even though she doesn't do anything important in the greater context of the story other than get some sex scenes. It's really ridiculous how completely permanent every single decision is esp. in the negative, it feels even rage inducing sometimes because it just doesn't make sense for a porn game to need to be handled so surgically/constantly consulting a walkthrough to not randomly miss out on something.
Additional less serious criticism, I would really definitely appreciate some kind of extra notebook function that allows you to write down the days of the week when you need to interact with so and so character, at so and so location, some things like that simply because it's not really possible to keep track of all of those dates and getting to each new day of the week is tedious. Additionally, maybe some way to fast travel between specific days of the week, like if it's a thursday now then I can use an option in my bedroom to skip to that date the same way I can skip to Friday after paying off the debt.
Final request, maybe add some cucking stuff, maybe bbc? It's not a big deal but I wouldn't mind it(Not with the male family members though, and not humiliation). Also more different scenes when you film in the studio, like when inviting Charlotte for instance I wish there was more than just the two scenes, especially the MFF stuff. Or allowing some mixing between the different things you can do in the studio, like putting on a certain outfit before making porn or inviting someone, or more options for what to do when inviting someone. The gym trainer should also be allowed to have her dick out while spotting you.
Anyways this game just has two big problems: the dissonance between the extreme cumulative/grindy nature of progression and the fact that routes close basically at the drop of a hat without guidance and the whole saving system being really annoying/inflexible. It's just a bit unintuitive and unforgiving.
