Hey, I enjoy what you have so far! Your systems all work together nicely and I had fun playing through it.
Biggest technical complaint is, I've made it to the end of the story content and now every combat is broken. Often, it won't even grab the correct characters and as soon as the first turn passes someone takes their entire lust value as damage and it goes to an unrelated end of combat. No idea what's causing something like that.
I would echo the (serious or not) complaints about difficulty. It wouldn't hurt for the easy mode to be easier. In a game like this, I am picking that setting to minimize the tedium and grinding and setbacks.
Regarding that, maybe I'm dense or just skipped over the explanations, it's not always clear how to get the results you're looking for. For example, I couldn't figure out a clear path to getting someone to agree to be my servant even if I had their flirtyness, arousal, and submission all at or above ~50. I don't know what the target numbers are and while really I do appreciate the complexity of the systems, I don't want to do algebra lmao.
Perhaps there could be a setting (or perhaps it is part of easy mode) that shows your odds of success with actions like that? Or if you want to abstract things, a "You don't think so-and-so will be receptive to this..."
In terms of polish, the main point of frustration/confusion I had was the fact that there was an Equipment option in the rest page and I had money, but I had no idea where to find equipment or what to use money on. Perhaps these things could be hidden until it's possible to utilize them? (Maybe they can be relevant with supporter cheats enabled, idk.)
It would be nice to be able to know where characters are (not just neighbors), though I'm not sure how hard that would be to incorporate into the map/interface. It would also be nice to have more ways to interact with characters who are following others (especially when they aren't servants).
