I just have one issue with this game - the MC hardly ever actually enjoys sex at all, I get its all powerr and blackmail etc but never once is she just horny or the sex is so good that she has fun... kinda takes the edge off for me but that's my personal bugbear.
You mean like what is pretty much always found written by default in almost every other female MC game story in existence? The overwhelming majority of which really never even had a chance to see a fraction of the instrest and success this game has gone on to see?
One of the biggest contributing factors to how this game has thrived more then most in this very niche market, to a point that at the same time it even routinely gets a free pass for having some of the absolute worst and most cringy writing you'll find in a renpy VN here, is that it actually embraces it's subject content without feeling a need to essentially apologize for itself.
I've said it before and I'll say it again. Content like blackmail is rape'y by nature, and therefor should feel and be written in as rape'y. If it doesn't feel rape'y, or if the dev feels they need to throw in some "but she secretly loves it" disclaimer to hopefully not offend anybody....then they shouldn't be bothering with blackmail themed content in the first place. Just pick something else that at least gives you the chance to end up doing it somewhat right.
