If I could make a game, I would effectively make a game in which every female character is just selfish, competitive and/or cruel, and it would feature a lot of CBT, psychological torment(cheating, lying, gaslighting, bullying, humiliation, blackmail, etc) and sexual torment(teasing, edging, caging, manipulating, etc).
I would make it a university setting where the female faculty is mostly female, so they mostly enable and cover up a lot of the misdeeds the women enact on the men. I would start of the game picking your stats, like height, strength, agility, intelligence or dick size, and this would effectively change the way the women see you and treat you. The more traditionally good looking you are, the more the women are possessive/competitive about the MC(exploring femdom from a position of desire, practicality or ownership). The less traditionally attractive you are, the more the women just want to reject, exploit or harm you for their own benefit(exploring femdom from a position of dominance, disdain or sadism).
It would be a very different spin on the traditional "harem" type VN, where the women are really the protagonists and the MC is just trying to survive to the end of the year. I would also probably add some stats/mechanics so the more of often the MC takes hits to the balls, the less effective he becomes with sex or other tasks, and possibly had a loss mechanic or path(s) where the MC can have his balls ruptured or broken. There would also probably be a lot of encounters of women hurting/bullying other non-playable male characters at the school as well(whether the MC does anything about it, does nothing or sides with the women would be up to them).
