Loved the idea, nice atmosphere with the color filter on, nice story, good voice acting, nice music. I enjoyed playing it, but ... the games seems rushed. Even after solving a puzzle, and being way ahead in the story, you can still see the old conversations. I found this pretty annoying. Also the game is fairly short. I would feel ripped off if i played the full price. But i got it in a bundle, so can't complain about that really. And some of the clues were given a bit too fast, making it quite easy to find out what to do next.
I restarted the last saved game because of the multiple endings, but was disappointed in the result of that.
No replay value , like with 99% of the point n click adventure games. I enjoy working on the Steam achievements, but won't restart the game to get the ones I did not get the first time. The game is simply not interesting enough for that.
So is it a bad game? Naw, I had fun playing it, and really wanted to finish it and keep playing, so that's good I guess.
Is it a good game then"? That neither because of all written above.
I can recommend it when you can get is cheap. But not when you play full price. I think paying 20 euro is absolutly too much. I would pay max 6-8 Euro for it.
