Level 147 is an endless mayhem of a seemingly infinite underwater system. All parts of the cave in this level are selected from 500 variants the level has custom made, and randomly arranged to create Level 147. However, this may or may not be true, as some rooms look entirely alike while others have major differences.
When you swim in this level, your body starts to be fatigued by an unknown presence, most likely of fear, so we advise to seek land. However, swimming for too long causes 35% of the insanity past this level, as reported by researchers, however, a great wave of relief is cast over you when you get on to dry land.
Every single fragment you swim in may or may not disappear, as if there is a human when the fragment reaches its expiration time, it refuses to reset, and this can happen forever. So, it is possible to swim through around 150 fragments, and only have 20 be the same as when you started the swim. Compasses and GPS locators fail and are severely damaged if attempted to be used.
Entities
The only entities you will find in here are weird, vampiric squids that transport diseases so quickly, a plague can begin in a small colony almost as soon as you see one.
