Tried it.
In terms of graphics (what I'd assume remains the weak link of the game) there's some good and some bad. When I saw the pics on the thread, I was afraid the guys had what looked like women's hips, but it's not really the case in-game (or maybe you corrected it since then). The models of the girls are ok (the FMC in particular), but the MC's face looks weird to me, as if he was smiling all the time. The sex scenes look quite ok to me, surprisingly.
The system with 3 kinks works, but it has some commited stances: no swinging unless netori, and a netorase content focused on the "stag" kind (the guy dominating). The later is ok for me, but not having separated concepts for swinging and netori (even if I like both) is a bummer for me. That being said, you can't cater for everyone, it's not really a flaw just a choice.
Also, the player has to imagine it's really different characters depending on the route, because they don't act the same at all.
It was a fun experience overall though. I dunno I liked the little fmc. Not really the mc though, maybe some work would be needed on the dialogues.
