#Short explanation

1. press yourself against a wall (i assume the wall is on the left ,so "a" )

2. move your mouse until you almost stop moving. try to find the point where it changes direction .

3. if you have found the perfect spot, ( ill just say you are going forwards) then you will press "w" forwards and while doing that keep pressing "a". If you were going backwards, do the opposite and go backwards, while pressing yourself against the wall.

4. Move until something blocks your path ( or earlier)

5. now after you walked all the way you will simply walk the reverse direction without pressing yourself against the wall.

6. repeat it until you clip the wall ( going back and forth)

7. dont move your mouse while walking back and forth. #video
