Chaos World

Chaos World (混沌, Konton, Chaos) is an area accessible from the Cloud Floor as of version 0.105 under certain circumstances. To successfully arrive here, you must use the glasses effect in Red Lily Lake after touching the flower with the reflection. This reveals red creatures that, when you use the glasses effect and one collides with you, you end up at Butterfly Forest. After this, go to the Cloud Floor and touch the only reachable NPC in the lower left corner and he will hit you off the edge and make you fall into Chaos World.
