If I might just say, this game did such an impressive job making me feel sorry for the protagonist that I'd like to formally request if this isn't the plan already that there be an ending to the game where the main char becomes more masculine, capable, bigger dick, etc and wins back the favor of his girl and maybe more. Sissification is fun sometimes, and the sub thing has its moments too, but I don't think I'd be satisfied until I'd helped this dude fix things and get the life he wants.
I'd even be okay with cuckold and sub and other more demasculating content and all that along the way to that ending, just adding to the narrative where you feel bad for this guy and want to help him, as long as he can learn from those circumstances and grow beyond them as an option for the player.
Keep up the excellent work in the meantime.
