Nox's scenes depend on time of day you approach her and the variant of the room. She has two variants, one with CV and other with few different types of fetishes. You can differentiate them from the position of Nox. You can change variant by leaving and entering the room. If the same variant appears 2 times, 3rd time is guaranteed to be different variant.
She also has her training scenes and mistress scenes which come after you've played 5 minigames with Nox and 5 minigames with Nyx. Doing so will start the sequence upon entering dorms.
Thank you so much, I'm glad you're enjoying the game
Of course, you deserve much more recognition for this piece.
On a more tangential topic, I've noticed a few bugs here and there, not sure if you were aware of these so figured I'd share what I found -
For whatever reason Aria's second CV event is a little bugged, if you get her hard enough to become erect, the red outline changes correctly but her penis remains in the semi erect state until you make her cum, then it will instantly revert to the flaccid state after that. It's not a gamebreaker by any means, but it is very odd, and as I quite like that scene is a bit unfortunate for me at least lol. Tested quite a few times to be sure.
Secondly, I found that with Hisako her UB animations just don't play correctly unless you were already inside her, and even then once you get outside of her it replays the same UB gobbling animation for every state of progress throughout the minigame. No idea what the deal with that is, but it consistently happens with her.
Finally I noticed that if you try to change your Odor Resistance that if you previously used the book of skills to change another attribute, say strength, that it wont let you choose a number at all, and instead will choose the number of whatever the previous attribute you changed was. For example I set my strength to 5, I got to change my Odor Resistance and it fails because I don't have level 5 odor, I switch to strength 3 and then when I try to change Odor resistance, it sets it to 3, which I was currently at.
As for the moment that's all I've found, hope this is in anyway helpful!
If I had a personal request, it'd just be do more of the CV, its good, and you only have dialogue for Aria, and I'd very much like that across all the futas, but thats more of a personal wish, rather than a priority of course. You are quite literally the first I've seen do any kind of bestial's and I *very* much approve lol.
But for real, overall the game works great, there really aren't any huge game-breaking issues I've come across personally.
