I'm sorry to say this but I hope the developer sees it and it resonates with him --
This is a beautiful game that runs perfectly, completely silky smooth on my PC. And it is an AMAZING concept that I'm absolutely in love with. There's just one problem: No amount of fapping is worth paying the same amount I could literally pay for a high-class prostitute in real life.
If this game is your passion, and not just money, then you're doing it wrong. If money is your passion, well... go for it I guess, but let me just say this: I'm someone who would HAPPILY donate money to you on an almost regular basis for a game like this- as much as my pockets could actually handle. It's an amazing project, and you deserve support for it.
But what I would not do is outright buy a game like this and I certainly wont be paying 50+ dollars for it. That's not to say that... over time, I wouldn't end up donating probably far more than that through regular channels. And that's where I think you've gone wrong. In today's day and age, you can make far more profit by allowing people to donate and support you in your continued endeavors of their own accord. But throwing in a huge paywall? That is the quickest way to earn an uninstall.
Just my "two cents," in the end, I think developers should follow their heart's desire and do them.
Side note, which is actually gameplay related feedback: I'm not a fan of the "love/fear" balance system. What's the point of owning a slave if you have to cater to their fee-fee's? It should be up to the player to determine how their slaves are treated, and there should be equal reward for either direction- otherwise we're stuck just doing the same shit with every slave. It makes for a stale, linear dynamic.
Having rewards for love, fear, and balance with different, custom benefits for each would make for some far more interesting gameplay, and would mean different "relationship" types with each respective slave. That would also open up the doorway for you giving the slaves different personality types. For example, one could be more responsive to fear, while the other is more responsive to love, and another that favors balance, etc. I could have a slave that performs well when afraid that contrasts another slave that is in love with me, etc.
