Great to know - I'm curious to see how the yandere will be implemented and I hope you do it well - also hoping they get a fair amount of screen time just like the other love interests.
As for pregnancy, when you mentioned creating under@ge characters did you mean that as in creating a child of a love interest? If so, fair enough - it's your story so you should ultimately have the say with how it goes, but just seeing it as an ending with perhaps a few love interests would be an extra touch of wholesomeness imo. If you do decide to include it then I hope you actually include a sex scene that leads up to this since it'd be something pretty intimate. Also just realised, the pregnancy tag would go along well with the lactation tag that you have currently - that'd introduce a whole new kink to the game.
Regardless of whether you include that tag or not, I still like how this game is going right now so I won't mind; it's got great potential. Best of luck to you, I'll watch your career with great interest.
