What to say about this? I'm not used to review too much, as most of the times you base your post on what you like so you tend to be not as objective as you should be.
Story is solid, the dev knows how to tell it, I liked the flashbacks and they helped a lot through the prologue, making it not boring.
Proceeding it makes you wonder what happened and what will be, not giving you the idea of what to expect.
That's what I call a good writing, when you just can elaborate theories not being sure of what to expect.
You slowly enter the inner part of characters, I bet there will be more insights on them.
Renders are really good, well above the average, and animations too (if you played it don't think about sex scenes just about the phone on the floor after falling, if you are going to play it check it out this moment and you'll get what I mean).
So far, I rate it 5 stars.
