I really enjoyed the humor in this game and even laughed out loud a few times. I was surprised that the author chose this particular genre for such ideas, since it feels like he's using his talent in the wrong place. I think he could've done really well with any fantasy RPG using this kind of approach. But it is alright, I'm not here to judge you. Do what you like, that's the best way to go in creative work. Personally, I don’t like depressing NTR, and I prefer games where we’re not too attached to the main character but instead focus on the spicy hidden sexual acts or the theme of seducing the heroines. A good example of this, where the pixel art us also key, is Boy Hero Ken.
Some other things I noticed: initially, I was pretty surprised by the antagonist's character and his relationship with the servants. I even thought the creator might be trying to break the usual clichés and do something fresh. But the ending in the latest version was kind of disappointing, and it seemed like things would just follow the same old path. I’d love to be proven wrong on that.
I agree with the comments above, that showing all the content at once isn’t the best idea. Plus, even though your pixel art is really nice, I can’t quite see what else it could do to surprise me. Without adding extra effects, like new sprites, additional zoom to see more details or drawing new poses from scratch, the scenes will probably all look pretty similar across characters, and that will eventually make things less interesting.
