I went into this thinking, "so its pretty much ddr with more arrows to hit, lovely", but its so much more than that. Lovely story, amazingly intuitive using keyboard arrows, and an all round great experiance. Get this game.

Yeah, fanbase for this game is annoying as hell, and I still think the original portal is much better in several respects. But its the best game to have come out in a long time and has one of the funnest co-op modes ive ever seen in a game.

Easily one of the best single player games I have played in a very long time. Plus it is undeniably the scariest game I have every played; the only other game that comes close to scaring me as much as Amnesia did was the original half life, and that was only because I was six at the time and thought the 3 headed green snake monster was the scariest thing on the face of the planet. Without question it is well worth the 20 bucks, and if this ever goes on sale and you don't buy this game, you should smack yourself 5 times and go cry in a corner for an hour for being so stupid.
