After the disappointing third game this one shines.
The controls are good, the puzzles are just what you expect, the voice acting solid.
Can't say much about the story without spoiling too much.
Sadly, also this time the voice of Kate Walker sounds completely different than the rest, like it was done with a mobile voice recorder. I don't know why they can't manage to bring her voice actress to the same recording studio as the others or at least send her a good microphone.
It still has some of the weaknesses of earlier games, like the hotspot locations. If there is a large piece of paper, why can't I just click anywhere on the area? No, there is one specific point on that piece of paper that needs to be clicked. At least that point is marked now when the mouse enters that object. This becomes annoying when part of the object including the hotspot is off camera.
If you don't like Sokal-Adventures, you should not touch this one, it's made in the same spirit, even if some of the weaknesses are gone. You got to like that style, otherwise you will be disappointed.
If you didn't play them already, grab Syberia 1 and 2 first, they can often be found discounted or for free. This game has many references to the previous games. Also this way you can see if you like the narrative style.
