Well, this game is pretty much perfect, with few flaws that I will overlook.
Graphics: Insane. the graphics of this game were flawless. I think it uses the HL2 engine sorta so they are comparable with graphics.
Sound/Music: Insane again. The soundtrack reacts to the certain things you are doing in the game and it always feels so cool. The computer, GLaDOS (I think thats how it is spelled) keeps hexing you and is actually funny sometimes. In fact, at the end of the game, GLaDOS sings a song, its pretty funny, and you can download it anywhere.
Gameplay: This gets an 11 but im gonna have to subtract 1 for the fact that there are only 19 levels. But, I'm gonna break this down for you even. The storyline is incredable. You are a test subject in Abeture Sience Labs, and you are subbosed to be testing the new gun that they made that makes portals. The computer is constantly talking to you which adds a little bit of a comic feeling as well as a freaky feeling, I mean it wouldn't be Valve without something freaky right? Well you go through these rooms where your main goal is to get to the exit. Sounds simple, and, in fact, it sort of is. I'm gonna go flat out and say this game wasn't that hard. This game didn't need to be hard though. You are so imersed in this game that you think you are actually in Apeture testing out this portal gun. The game forces you to think outside the box and then switches it up, and makes you think in a more classic puzzle solving way. The game only takes about 2-3 hours the first time around, then if you feel the need to play it again (like I did) it'l only take you about an hour.
Ok, well pick up this game, in the orange box or just on steam, you have to play this if you like puzzles, if you like FPS, or... actually just play this game.
the cake is a lie
