The RedRooms

Description
This level is one of the most mysterious backrooms levels. Passing through the monochromatic yellow corridors, with a small probability you can meet red corridors that look into a room similar to level 0, but it’s red. Almost nothing is known about this level as none of it has returned. Those who were able to return back to level 0 talked about strange knocks heard throughout the level. As if someone wants to reach out, but the source of the sound was never found. It is recommended to avoid places from which the sound of knocking is heard loudly. Also stay close to the corridor as you might lose it due to the level's non-Euclidean geometry. If you lost the corridor back, then maybe you will stay at this level forever. Due to the mysterious nature of the level, many researchers create theories and rumors about this level. Some anonymous said that they saw dangerous entities in the form of shadows. But this cannot be confirmed.
