how enter to this level:

how escape from this level:
you will not have time, you will die from carbon dioxide within 2-3 seconds.
well, if you are wearing a protective suit (I don't know how), then to get out of the level you need to close your eyes for 2-3 minutes. and you will return to the level of 9223372036854775807.
there is one flaw in going back…
you will return to the beginning of the entire staircase of level 9223372036854775807, no matter what floor you were on.
the level -56307583427 is something like a maze of stairs leading to the so-called "episodes" on the "episodes" there may be with some rarity chairs with negative gravity, due to the fact that the chairs are on the backs. also, the stairs can be inverted or standing left or right sideways.
the level has carbon dioxide, so if you hit this level, then you are very unlucky.
