okay so imagine you have the super power to turn into a ghost at anytime and travel through a separate realm where you can spy on people and sneak up on them and travel anywhere undetected, and travel with speed.
so thats what this script does
with that being said, these are the controls.
press x to toggle ghost mode
 use wasd and q to go down and e to go up 
also press + to speed up, press - to go back to normal speed.
k enjoy
also, this is a universal script so you can use it in almost any game
