First time I saw that I nearly puked I was laughing so hard.

That video is great. I'm actually playing Portal currently and on level 18. I loved back a level or two when I got to stalk and destroy those guys!

Now if I could only figure out how the hell to get through these last two levels. I hope there's cake!

I'm stuck on level 15. Any help?

which bit are you stuck on?

Remember how to doublefling (Ie, shoot a portal onto the floor as you are flying through the air) to get more distance.

SSY posted a much better, and more subtle reply (hello, SSY) just as I was hitting "Submit."  My reply is basically to point you to a place where you can cheat yourself out of the joy of a game like this, by getting a solution handed to you.  So I'll put it in 'spoiler' tags, and you can look at it if you decide you really need it.

[spoiler:20zeaa2e]Most of the fun in this type of game is in working out the solution yourself, and the sense of achievement that brings.  However, at a certain point, the boredom and frustration cancel out the fun.  In my opinion, that's when one might consult a walkthrough.  Try to avoid simply watching all the walkthroughs and following them: often you can find entertaining little details in the game that walkthroughs ignore, because they are just about getting through the level, not enjoying and exploring the game.  And in fact some of them are posted by gamers who obviously have way too much free time, and want a chance to show off their awesome skillz.

With that in mind: A Portal Walkthroughs page[/spoiler:20zeaa2e]
