Writing, story, porn and content is all good, why 3 stars?
The decisions are impactful, that's great, the issue I have is that they are way too impactful, or to clarify, the slutty route go too far too fast into being a mindbroken fuck doll.
The only sexual encounters are with goblins and if a woman ingests their cum in any way they are instantly addicted and mind broken, see the problem? From just smelling it they will crave it, having it on their skin will break their will and getting it inside their body in any way will break their mind. This drastically limits what interaction can the MC perform inbetween, the dev deals with it somewhat, but there is a limit of what they can do in such a confined setting. -1 rating for this
Second -1 was personal, as I don't really enjoy the drugs/hypno/mind break the aforementioned setting was a slight turnoff. Still, if it was done properly I wouldn't mind it that much, but with how extreme the change in character is I couldn't ignore it.
If you are into this stuff, the game is 3.5-4/5, as I'm not it's a 3/5 for me.
