... it's a good game, the story is OK. Still, I realised it failed to actually fascinate me. I'm not sure why. Maybe it's the plot, maybe I'm too old for its dolls and other child aspects. I played it for a short time, then quit and continued a day or two later.
I can't say anything against it. There are no obvious weaknesses, but for my taste, it lacks actual strong points.
I bought it when it was on sale at a reduced price so I did get my money's worth.

I liked the first 1000-doors game very, and this one is equally good. I'll surely will play it again, trying to avoid the hint button :-)
I do hope for a sequel ...

Sorry, I didn't like it.
First of all, I hated the lengthy interruptions with 'real-life' characters – without any skip option. What they had to tell wasn't at all interesting.
And it was extremely boring to search the same rooms over and over, without any useful hints. Luckily I found a walk-through somewhere on the internet, otherwise I wouldn't have been able to complete the game.
If you're very young or easily frightened, the 'horror' elements might be a mild thrill. For me, they weren't.
There are many much more interesting games at the same price.
My recommendation: don't buy it. It doesn't get better after the free trial period has elapsed.
