I'm extremely happy to see development going so well, and the variety of content that is being added looks extremely interesting.
I will admit I have been waiting on retrying the game due to how dry the writing is during the core gameplay loop and early game.
The smutty evidence system and huge variety of media for the ghosts groping and gradually having sex with the protag over the course of a hunt is excellent, but most of it lacks any writing or reactions on her part.
Since evidence collection and the generic ghost events take up the majority of the game-time, I feel that part should be emphasized more in the writing to make the game less repetitive and more exciting.
You could also get really creative with it, like having specific reactions for individual types of evidence/foreplay that progressively get more depraved the more used to it the protagonist gets.
When the ghosts cum inside her mouth without her realizing it, her discovery could go from shock to yearning to relishing to addiction.
The spirit-box could be used for call-calls, or maybe remarks as she becomes a more famous and notorious slut among the underworld.
Sex stats or traits that don't have any gameplay effect, but emphasizes her gradual corruption in an "appearance" tab as she becomes familiar with different types of foreplay and sex, or as certain body parts become more sensitive, would add a sense of permanence without needing much in the way of content.
Ambitiously, companions could have their own reactions that change overtime, or conversations between them, and a much more corrupted protag, as she reminisces on the naivety of being a rookie ghost hunter.
Hopefully such a blatant wishlist isn't obnoxious, but I think working smarter not harder on content that is often experienced verses one-off or situational events would greatly help the game.
I'm really glad to see how much support the game is getting! Great work!
