How to get stuck when crossing the firewire biochemical hotel bug?

Stand on the white pillar of the slide, hold down the shift key and walk back slowly. When you find your body in the air, just press ctrl, that is, squat. Give points! ! I'm teaching you super jump, ghost jump and card box. Be sure to give points. Super jump means holding down W+S and shift and clicking jump every 2 seconds.

There are two kinds of ghost jumps, one is specially used for people who can listen to footsteps, that is, press shift+Back+ squat+jump to save, or squat jump.

Then the card box stands at the corner of the box (it must be 90 degrees), then press shift to the left and right, and then press Squat to get stuck when you get in.

I typed so many words, I'm sorry if you don't give points! !
