I played this game some years ago. It's a beautyful journey inside a man's mind where you will fight against its fears and feelings.
It is hard to tell something about the game without spoiling something about the story, let's just say that you will need to change character often in the game (if i'm not wrong you will play as four different characters... or just one?) and every change will bring a turn in game's atmosphere and dynamics without ever going outside the point and click adventure style. Weel, to tell the truth there will be a pair of combat scenes but these are extremely easy and you will not pay any penalty dor dying, not ever starting the fight over.... but you will see it yourself.
As I said this is a disturbing game, not much (well, not only) for what you see as for what what you see involves... but, again, I can't be too much explicit without ruining your experience.
All in all, a game anyone in the right age (I would say the minimum age for playing is about 14) should play this game or, to say it right, make this voyage in a human diseased mind.
