This cube will test your 3D perception skills. Remember: The best way to start is look for the grey roads so as to find hidden roads in the mirror cube.
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.
