The narrative is outstanding so that I couldn't stop and swallowed it in one go. Can't say there was any horror for me, but there was the rest spectrum of emotions.
The gameplay part is simple and intuitive. Pick, mix, use objects - you know.
Sometimes you will have lots of dialog choices and despite the fact that most of the time it doesn't affect anything you will get appropriate response and it feels a little like roleplay.
It still does have a lot of decisive choices so that it has a little replayablity.
In fact, the game is so attractive that it will be really nice to play it again one day. Like re-watching a wonderful movie.
