Pros:
+Great graphics.creepy but the same time really beautiful.
+Really spine-chilling.It's not about zombie or ghost something supernatural,it's all about a painter's mental illness.his imagination and nightmare.So this game is type of 'mind game',things what the protagonist can see are shifting strangely.One second you are in one room, then you turn your back and everything has changed. that will make you feel a chill of fear.
+Multiple endings.You need to do or not to do particular things to get the particular ending.
Cons:
-Opened too many doors.
In short words:
As a horror game,it's absolutely successful,I was totally scared by the atmosphere of this game.I couldn't play this game for too long time once,I was so scared that I just felt uncomfortable.
