Short and sweet, yet another titan of its era, valve went out of its way to go from releasing shooters to dip their toes in the puzzle genre and they absolutely nailed it. This game is as close to perfect as I could call anything. Listening to the developer commentary post game made me realize just how much thought and passion was put into this game and you can feel it every step of the way. Everything you are taught is taught in such a smooth way that it doesnt feel intruding, the aspects of the puzzles are used so well as to where nothing ever feels like its over or underutilized, the writing is great and the storytelling is done in such a way that it doesnt feel intrusive or forced in your face, it genuinely feels like you are there experiencing it as the character. Amazing experience.
