Level -30

Description
Level -30 is a huge skybox containing floating islands. During the day, it is safe, but at night, it becomes infested with entities known as night demons. It has been reported that these entities form huge flocks and can attack very aggressively. They are also 10 times faster and more powerful than an average human and can easily catch up with you. For this reason, it is recommended that you hide somewhere in this level to survive the night. There is a very unusual grass in this level, the usual grass that grows on each island is emerald green, but in some areas of the level, it changes to dark green or blue. Blue grass for inexplicable reasons gives a sliding effect like on ice. Dark green grass reduces the effect of gravity, which makes it possible to jump very high. MEG investigators report that white trees without foliage grow throughout the level, and these trees are stronger than those in frontrooms and even equal to concrete in strength

An entity called whiteness is the main food source, and they have almond water instead of blood, as well as being everywhere on this level, so they can easily be found.

The level also contains emerald deathrats, who live in mines and, for some inexplicable reason, walk alone rather than in flocks. Also they are still very dangerous because their teeth can dig through metal and their skin is bulletproof. So it’s recommended to avoid any mines in this level if you don’t have a good equipment.

Entrances and Exits
If you stay in Level 999 for long, you may find a black, rusted door with the world "S3C0ND W4Y". Enter it and you will be here. No-clipping into an emerald in any cave level will send you to Level -30. Following a staircase that is surprisingly placed in Level 10 will eventually send you to the island, the staircase will disappear shortly after. Those who have tried to go back have never returned.

Falling through the sky will send you to Level -30.1, although you can be rarely sent to Level -31. Finding a concrete cyan warehouse and entering it will send you to Level 70. Jumping into a lava pool in any of the mines will send you to Level 666. Riding a rusty mine cart will send you to Level 3 or Level 8.
