In anticipation of The Orange Box release in five days, here's the distribution files for something I was working on several months ago, called CODENAME: Portal. It's a spinoff of the upcoming game, Portal, except in 2D (similar to CODENAME: Gordon). I do realize it's a little bit buggy and might be slow, or might not work on all operating systems, but whatever.
For YouTube videos, look a couple of posts down.
