[Written after playing version 0.2.3]
It's still relatively early in the story - there are only two real sex scenes (plus one fantasy blowjob and the start of an exhibitionism arc) - but the writing and mechanics are great, and I'm excited to see where it goes in the future. When I read that the you were trying to make a more "grounded, realistic" game, I was skeptical that you'd be able to pull it off because so many authors of adult games seem immature or have a less than perfect feel for interpersonal relationships. That's not much of a problem in a game that doesn't take itself completely seriously, but I could have seen it being an issue for this one. When I found myself actually enjoying the story and the depth of the characters, I was pleasantly surprised. In particular, I like that in some cases things get emotionally messy after a character indulges their kinks. Rather than having sex always be a driving force of change, it's treated as just one of many factors in the characters' evolving interpersonal relationships. It's a mirror or a lens rather than a panacea.
Mechanically, I really like the kink skill trees and their connection to dialogue options. I also really appreciate that there are appealing dialogue options for each of the personality traits - when I originally saw the skill trees, I was worried that I'd have to choose dialogue options that I didn't like in order to experience kink content that I do like; it would have made the game worse to have only been able to experience some kinks if the main character were someone that I didn't like.
The game also explained chess in a way that was interesting to me despite the fact that I'm a beginner and have never really had any interest in it, which was also an unexpected pleasant surprise to find in the random adult game that I downloaded on a whim.
Overall, very solid game, and I'm excited to see how it grows. Great job!
