Crypt of the Serpent King

A lot of people have problems with the jumps in the game and in particular with this level.
So i found something i wanted to share, that helped me alot with this level.

The platforms the keys are on, all have the same layout.
I made a sketch that shows it: http://imgur.com/a/nGcL3
What helped me was:

1. I always jumped from the "O"positions, never from the "X" ones.
2. Picked up the key,
3, Looked down and ran straight to the next circled area ahead
4. Jumped at the point of the "triangle".

As soon as i started doing it this way, i never failed a jump.
Hope that helps a few people out there !

The only help i can give for this whole game is that the platforms on the third level are 10 times harder than the platforms in the other levels mostly because they're gradually raised which means when you go to jump off the platform back to the normal floor you have a chance of kinda run glitching and your jump doesn't count and you end up running into the lava so my only solution is to VERY slowly walk down the pointed edge of the platform until your near the end and then jump. Also running before jumping doesn't do anything so avoid running as it can make you fall into the lava.
