Ahh! I loved this, and I'm really looking forward to seeing where it goes now!
The art is amazing, I really like the aesthetic, and the characters are all so beautiful. Also I feel like it does a really good job of including enough CG stuff to give impact to scenes that deserve it, and in visually interesting and varied ways too.
The story is really good too. It does a good job of balancing the realistic aspects of the story with the supernatural. Honestly the egg hatching scene in the first chapter could stand on its own as a really solid short romance VN.
And I kind of enjoyed that it's really not shy about its influences. It feels like the explicitly queer version of all those anime/games that we deserve!
Also, I played this right after the demo, and I was impressed by how much it was improved, it fixed pretty much everything I was unsure about the first time through. (Depending on how much effort it would take, it might be worth backporting into the demo release.)
One minor point I noticed: At a certain point everyone just starts using she/her for Kite, which felt right, but it also seemed a little odd that it was never discussed (unless I missed something) given they were so explicit about that earlier.
