I quite enjoyed this. It's interesting that the studio took a different direction by making this as quite a dark game. No comedy unlike their previous games. However unfortunately I found it quite short, lasting only 5 hours by my clock. I suggest if you like adventure games to only buy this on a sale as the twists in it you don't see coming.

Edit: Game length really doesn't determine the value of a game. The fact I can remember the story to this after so many years proves that it was a deep and impactful story. It's a little difficult to explain as to why without some major spoilers, but it takes the whole classic amnesia set up and the puts it on it's head as the guy tries to figure out who he is.
