I remember going over to a friend's dorm and watching him do a speed run of Portal when it first came out, yet somehow I forgot that I'd actually played it myself until I was over halfway through the game this time around. Weird how memory works.

Anyway, it's just as great of a game as I didn't remember it being.

Portal does a great job of teaching mechanics, has a great central conceit, and has great humor. There's only a couple of small things that keep it from five stars for me. Primarily, the game just doesn't go quite far enough with the concepts for my tastes. I'd like a bit more of a challenge and to see the ability used in a couple more ways. The only other complaint is that the portals are a bit skinny which makes some execution slightly more annoying than is necessary. That's really a nitpick, though.

A certified classic.
