Tried it and liked it well enough. Fair amount of content for a first version.
MC could/should be less of a creep, or rather stop sending completely different signals.
Kailee is sweet, but doesn't seem the completely naive and demure type (unless what happened to her, will be the reason for changing her character), which would certainly be a departure from how the daughters are often depicted in this type of games.
I like it, it makes her a more realistic and rounded character.
In many good ways, this reminded me of "Our Fate" a game I loved, which sadly never got finished, because the dev disappeared right around the time the final part of the story began. I've read in one of the reviews, that the devs initially worked on a remake of that one, so it's no coincidence that Lost At Birth reminded me of Our Fate.
The only thing I really didn't like were those stupid "title card"-cutaways. They took way too long, I went to skip them every time, but that mostly led to losing some of the writing, because it transitions directly into the next scene.
Really a weird way to do this. Why not make it so that you can just click those away, with a single click? It doesn't take you ten seconds or so to read a few words, when nothing else is on the screen.
Minor problem, so not really a dislike, is the characters apart from Kailee, like I already wrote the MC should dial back the pervy part of his character a bit, and neither his wife nor co-worker are in any way sympathetic characters.
Now, this is of course just my personal taste, but I do prefer to have some characters I like in a game.
Hope this doesn't seem too negative, I really liked the renders, the girls look great, and the writing was quite good as well, with a few minor weaknesses. This game is definitely off to a good start and could become really exceptional if it continues in this quality and with reasonable time between updates and acceptable length of each update.
Edited to add: Okay, read a post by one of the devs now, so obviously MC is supposed to be a sex-addict, he doesn't perv out over talking with his daughter, he just constantly pervs out. I actually find that better, I can certainly see the appeal behind the idea that he replaces one addiction with another one.
