This cube was designed to test the ability to simplify any puzzle which looks complex...and to test the strength of the radiator. The results were conclusive: not very...
We also apologise for the lack of light at the lower level, the anti-matter is causing some interference with the power. The attack was clearly planned and we are trying to find the culprit but in the meantime, you may as well test some more.
Information:
(Previous rules from the other testing partly apply, though some mechanics such as gravity do not appear in this facility)
The mirror cube and the reality cube can have slight differences, for example, portals are not in the same place.
The reality cube can have paths that appear invisible in the mirror cube, so both, essentially, become mirror cubes.
