Without spoilers is a review here very difficult, because the game is able to score primarily with atmosphere and story. The gameplay is actually quite simple, is limited in free play mostly on "walking / running" and interactions using right stick in cutscenes on Quick-Time-Events and keyboard shortcuts.
This may be a deterrent for many, even I was not sure whether I would permanently not be too monotonous, but my concerns were unfounded. I was the game personally blown away, the atmosphere is gigantic, one feels in the middle of the action. It also happens in the control that one commits serious errors. And not by accidentally pressing a button, but by a quick cut cut-scene where you walk in to "panic" a decision, so that you did not want to meet ... and then after you see the result of his actions, wants to undo it ..
And that's the point, here there is no turning back to level start, here you do not have 3 lives up to the game over, here it comes to decisions and consequences, the game goes on, the direction changed, in short, it is to the right ajar life, if technically possible.
Whether one suits this kind of game, is a matter of taste. Hard facts: The graphics are pleasing to the eye, the sound comes bombastic. The rest is in the eye of the beholder.
I was the game from the outset cast a spell. In my opinion, a new genre was created by adventure games into 2010 to convey, I hope for more of this type and was entertained.
Finally, if I would like to mention that the 2 episodes from the demo are rather average failed for me someone interested. In the complete game wait since all other pearls can be seen from the times rather sluggish prologue somewhat.
One last compliment to the developer for all ideas, including the idea of how to bridge the installation time :-), something different, but I do not want to reveal too much.
