Portal - Levitation
 

I was playing this game just fine until I got to level 18 where you need to propel yourself high enough to reach upper platforms. ..well I couldn't do it so I created a moon-jump.

The game really doesn't need any cheats but it does tend to give you a headache popping in and out of portals at diffferent angles so this may prove useful too others.

It's very simple to reach the upper levels, when you know how to do it.
I was also stuck in this level at this position.

Then i found a youtube-video for this level: http://www.******************?v=0G7hjTfWiho
The player in the video plays the levels as fast as you can. So you have to always press the pause-button, to see the solutions.
When you know where you have to drop the portals, then it's very simple.

Holy crap! ..now that's amazing. Even with the lev cheat, I wouldn't be able to pass the level half as fast as that dude.
