Thanks! The NEET is actually pretty darn boring/underutilized in the original game, so I added a ton of dialogue for him, as well as the aforementioned ending and story branches. In terms of character development, the game also had him flip-flop between being a "hero" type or a "betrayal" type of companion, so I tried to elucidate those paths by directly allowing the player to dictate his path/ending.
I think it's somewhat tricky to strike that balance of difficulty in H-games; your audience can range anywhere from, "it's too hard and I can't beat it - plz give me cheats and saves", to "it's too easy, it's getting too boring and playing has become meaningless". Either camp will complain vociferously, and obviously, this is a problem in the broader element of game design in general. If you're looking for more survival-themed horror games, I'd recommend Bioasshard for a 3rd person shooter RE clone, or Found Dead (which I just translated) for a RPG horror game with more story and replayability (through lots of extra content and story pathing).
However, I agree. Getting pregnant intentionally is a strategy that isn't often utilized because the game's too easy to warrant it unless you actually have a fetish for it. It would've been intriguing to have the player face that dilemma but given the fickle nature of the game's demographic (aka the "can't please both sides" argument detailed above), I suppose it was simpler for the game devs to make the game easier than harder.
