So I was just busy speed running a few levels, when I did something that gained me a lot of speed. It kind of works bhopping in CSGO. You hold down your w and a or d keys, and making a slow turning motion with your camera in the direction where your character is going (a or d). Here are two examples of me performing this tactic.
The long hallways are points where you can use this tactic.
The starting wall jump to platform maneuver can be skipped easily, and the rest of the level can be plowed through too.
Muahahahaha
