I hope this helps like feedback:
I like the game and I really want to know more about Felicia's story but... I have some troubles with the recent chapters:
1) The chapters feel unconnected, it's like every chapter are self-conclusive when the idea (At least I feel it like that) should be continue one unique story chapter after chapter.
2) I like the new characters (Especially Felilia's design) but the story is about FELICIA, not other characters, I think it's better save them for other games like spin off or make them appear in the background but not let them stole the protagonism to Felicia.
3) The idea of the game in the begining I thought the game was NTR but the game is NTS in every moment and I don't dislike the story but, I think the game need a really more definited NTR path separated of the NTS I mean, the MC NEVER must know what is Felicia doing, the name of the game says it all, "Damn that's Felicia" in plan "I don't think that she is" like any classic NTR where the MC watch a censored image of his girlfriend/mother/wife/sister/Childhood friend/etc, and he can't believe that is his girl until the end where she can't come back to her old life after be too much corrupted.
The solution to all this I porpose is:
1) Rework a little the story to conect better the chapters.
2) In the next chapter and from it all the story must spin around Felicia and ONLY felicia, with some characters having a really little and short participation to not make this all only with Felicia and the MC.
3) Rework the game very much than a little to make more clear the NTR path.
