What's funny about The Fifth Personality?

Player interaction. In the fifth personality, the funniest thing is the interaction between players, such as the blind girl who repairs airplane seats, and the air force mercenary who repairs airplane slippery seats. For example, the raiders said that the merry-go-round was knocked out by the red butterfly, etc., all of which belonged to player interaction, and turned the fifth personality, which was originally a horror escape game, into a plot game.
