I need to "like the protag" or at least feel they're relatable because without that, it's not fun for me to read. As for humorous, maybe I just take it a little too seriously because I suppose it's meant to be taken seriously in-world, to a degree. I didn't say he needs to become a better person in the story, but I think he can make people grow and stuff without being so damn selfish about it.
And if you think my expectations are a bit out of place, I'd like to direct you to a fat VN called Worshippers of the Gain. That has you going around encouraging/directly fattening others without being a jackass, and it's plainly all about the fat stuff. Not too much character stories, it's all horny stuff. It helps there IS an overarching story, but the point I'm making here is you CAN make a fetishy VN with what I'm expecting and STILL have it satisfy what you're looking for.
Keep downvoting me all you want, it's clear you just disagree with what I said and have an entirely different idea of what this should be like. From the start, though, I wasn't looking for YOUR input, but the creator's. If THEY say it's meant to be how it is, then I'll respect that. It honestly kinda sounds like you're telling me I'm completely wrong and stupid for expecting this out of the game/story, when it was all just my opinion to begin with.
