Moving in Zero Gravity?

Hey,

In order to do a gravity jump, you have to take aim like your going to shoot aim for a flat area and press the gravity jump button .... in my setup I right click to take aim then spacebar to gravity jump ... if you cant jump to where your aiming the game will make a noise and the target goes red for a second.

(If i remember correctly level 2 is where you have to go directly across the way in a spherical shaped room .... your just going to aim just above the door on the opposite side then from there aim and jump for the platform just in front of the door , or just jump up to the ceiling than back down on to the platform )

thanks
