The Artificial Dimension of Illusion (updated v2.1)

This map has been fully inspired by a game Antichamber

The Artificial Dimension of Illusion is a legend of transdimensional engineering. The engineers were trying to design a shelter which interior could be placed in another dimension. So, they went up a little house that was much, much bigger inside and the interior was located in a four-dimensional, non-Euclidean space called "the Artificial Dimension of Illusion".

BACKSTORY: in 19th century, german physist and designer, Charles Carol Pabblingdonn had got an idea to build a shelter that could be bigger inside than outside. The problem was that physics doesn't allow these phenomena exist. But it wasn't an obstacle for Pabblingdonn! He managed to make kinda hole in space, a portal hung in the air and leading to an empty black dimension. There was nothing in this dimension, so he and his engineers designed the interior of the shelter and in 1812 they officially finished their work and Pabblingdonn called the new dimension "the Artificial Dimension of Illusion" or "the A.D.I.". This dimension was unusual, it was a four-dimensional, non-Euclidean space. It could change an appearance of any room at any time, almost all doors and passages were seamless, and some rooms were placed in the same position without touching themselves!
