Wow, impeccable writing....As someone who's a huge fan of exploring more "dark" character psychologies, I really, really loved this. Often in real life, you hear things about these sorts of relationships where the person in Liber's position may say "When he's happy things are good. He only gets angry sometimes" and things along those veins. (Along with the manipulation and almost purposely looking for a reason to be cruel, of course.) It really puts into perspective how easy one can fall into this mindset of accepting certain things and rationalizing certain things because of the love bombing that follows. When you're on the outside looking in, it's easy to tell people to leave, but this gives a really nice perspective into how easy it is to rationalize things when you're in the position.
I found "Master" to be rather tame in comparison to similar characters I've seen, but then again I wonder if even me thinking that also proves my above point because there's really nothing tame about not wanting someone to leave a room. I think people in Liber's position in real life use the same justifications with thinking things like "oh well he only does this to me, that's not as bad as it could be" especially since mental/emotional manipulation is brushed off more than anything physical and seen as "not as bad." Just really interesting and put things into perspective.
This is the first game I've played by you/your team, but omg I hope you consider making more and lengthier projects with dark psychological themes like this!
