How did CF Biochemical Hotel sink in?

I'll tell you, but I hope you can give me more in return. First of all, if you are stuck in a corner with a beach chair, you should walk to the right of the corner, and be careful that it will come out and go straight until you come to a lifebuoy and face the circle. Then you will fall, turn around immediately, and press _ _ w+ jump _ _ to go up as fast as possible.
