So, another comment -- this one a little more broad and revolving around the core mechanic of sex and slavery in the game...
First, I like that the MC has a sex drive that is always increasing and (presumably) has to be managed. I never got past "throbbing," but I took this as a serious motivation and acted accordingly. However, attempts to sate that drive ran into a serious hurtle with regards to the slaves he owns. He took them for long walks, bought them chocolate, raised their arousal to level 20+ only to be turned down cold for sex -- more than once, and never bringing their level of affection beyond "neutral." So... He resorted to more severe means to achieve satisfaction, which poisoned his relationship with the slave in question, of course.
A couple of points regarding this situation:
In desperate, apocalyptic setting presumably awash in sex slaves (to judge by the goods the vendors sell, if nothing else), why aren't their prostitutes -- willing or otherwise -- available? Only judging by the new v0.7 screen captures, it appears that this has been addressed at least in a singular instance... Still, this seems like it should be a much more substantial component of the game world.
More broadly, however, I would suggest you might want to re-think the mechanics of the MCs relationship with his slaves... He seems to treat them better than your typical Tinder hook-up and gets no satisfaction. I understand you're trying to emphasize the need to build a relationship between the MC and the slaves. However, this seems to go too far.
In a savage, lawless world if a property holder offers a female slave a choice between his bed (for otherwise non-abusive sex) and the whip -- the overwhelming majority will choose the bed. The slave might not especially enjoy it, and it won't necessarily lead to an affectionate relationship between them, but there is plenty worse the MC could do...
To address this issue, I would suggest you expand your relationship model between master and slave from a single axis defined along a continuum between love and hate to a multi-axis model, which would add at least one more variable, which I've tentatively labelled "numb":
The idea being that if the MC insists on sex with a slave who would otherwise be unwilling, she nevertheless goes along with it, but grows more and more emotionally withdrawn -- harder to teach and engage with emotionally, but docile. Given the MC's strong sex drive and seeming inability to persuade (!) his own slaves to have sex with him, it seems like some type of re-think is required here...
Thanks!
