Just a little feedback, as I haveonly completed one route (currently on male family friend). So far I'm really surprised by how much I enjoy the game and how you can tell there's dedication behind it. Got here for the lewd and stayed for the rest.
1) All the more reason to give that feedback, because it really stood out to me how often a conversation contains a dragged out "are you okay with this" type of exchange. Since our character is portrayed (and called) "empathic", in most of the scenes he/she would know if "it is okay" after the first time he was in a situation to ask that question. Anticipation and Resonance. Especially if it's about something way less intimate than what already might've happened. No problem with a rhetorical courtesy question, but it really is often.
2) The POV closeups tend to look a little weird to me. The models are beautiful, the pictures compositions are top notch and the animations good, but with all the characters looking sleepy all the time (and at least the male family friend being a good amount taller than other characters), most conversations look almost a bit like a fisheye portrait for 60% of their duration.
I'm actually in awe how well the facial expressions in most kissing scenes are and I think the game would benefit from more borderline 3rd person shots, at least in animations. Maybe a camera height/focal length adjustment could compliment, I'm not a pro.
3) As for the Ava scene:
I like the cinematic approach. Not being able to skip or stay with a certain frame/animation is unusual, but it does emphasize on how it's "happening". I also like the approach to it on a more emotional level and I can already see you're taking a big swing for that. I'm eager to see the full thing!
Insert my POV closeup critique here aswell.
The overall music is also great by the way. I'll give more feedback when I feel like I earned the right for it. But the potential and structure (hell, 30 days) is massive :D
