Portal... in 2D!
Portal is one of the greatest games of all time, you know that. Of course it is. Valve published it.
Now, since it was a far too short game anyway, play this - Portal: the Flash Version, a professional-grade fan game. I'll go as far as to venture and say that it's far better than Codename: Gordon.
Highly recommended. Playable online at http://portal.wecreatestuff.com
