Just finished it, unmarked spoilers below.
So I think I get what this game wants to be, and I enjoyed it when it was firing on all cylinders; paranoia, red herrings *everywhere*, but still a dead body in the mix provide legitimate mystery -- at the core of it two people who are engaged with each other and disengaged from their real lives. And Ned, not dissimilar from them in how he has tried to handle his own crisis.
Throw in a few naked girls, a fire, and some people doing science, and you wind up with a story that ultimately goes nowhere, but is somehow exciting in the process up until the end where all is revealed, you feel silly for thinking some of the things you thought, and put it down.
But as others have said, the game leaves you empty at the end. There's no more mystery, and no wonder, and none of the characters have grown in a major way. Maybe, maybe the point is that after all the escape and late night conversations, you have to go back to real life. So Ned is going to have to have all the conversations he never wanted to have, Hank gets to go watch the love of his life fall deeper into dementia and a painful death, and our lady friend on the other line goes.... and presumably is forced to find some other way to spend her time.
It's uneventful. And maybe that's the point. But if so, it's a kind of sordid point to make. Maybe because so many players are going to want to see their characters grow, have a eureka moment, or uncover some crazy truth that just isn't there.
What your expectations are within the first 10 minutes of the game will probably determine whether you even like it. Which feels kinda bad, because the first 10 minutes point in a wider, more interesting field of view, and the ending here is so narrow-minded and -- for lack of a better word: boring -- that it feels like getting cheated out of an adventure. That said, an adventure, I guess, you were never promised.
Mechanically I didn't like *playing* the game all that much. A lot of walking, and climbing, and jumping down pits, and hacking down trees -- none of that is anywhere near as good as the talking that happens, so it feels like background noise to me. The game is pretty at times, and lifeless and boring other times. I got lost a few times, but when you realize the world isn't all that big to begin with its easier to deal with. The core of the whole thing is absolutely Delilah.
The problem is, unlike say Soma where your female companion grows and reveals herself and her ambitions, and becomes truly a character, Delilah never really does; she just seems like she is, because her voice actress is amazing and the performance is pitch perfect. There's just not much to say between the two, which feels a shame. But it's not their fault, I guess, it's more mine for assuming they had something to say to each other. And if you don't feel entitled to that relationship becoming something it's not, then there's a lot of fun to have here.
Otherwise not so much. The thing I liked the most about the game didn't go where I wanted it to, and I don't want to complain about it because it feels like it was my own expectation that was wrong. Still, up until the last few minutes, I enjoyed it.
