Cosmic World

Cosmic World (Cosmic) a.k.a "You went through so many dark places, now I'll burn your eyes with my bright colors" world, is an area reachable from the Old Train Station.

Features
Very very very bright. You start off from a building that you can leave through stairs going down (if you can see them). The place appears to be a rainbow island surrounded by flashing water, going through you'll eventually find a small building that leads to a dark room with bones attached to the walls, a bench and a lamppost, and a rainbow flower on the ground. Stepping on said flower and facing the wall, you can chainsaw it making purple "blood" splatter.

A brown rusty building is found by going south from the entrance and leads to Square Ruins

There's a very well-hidden vending machine and an NPC somewhere around this area.
