Easy wall-jumping!

[Kaith]

If anyone is having difficulty doing the wall jumps for the twin pillars towards the end, I found an easy way of doing it.
Back yourself up against a pillar and make sure you're lined up with another pillar in front. Keep your camera facing directly in front and only use your spacebar to jump up. You'll end up at the top eventually!

Yay, saved me some time. I used this as often as possible to reach some of the collectibles.
