But this is totally out of left-field: in Quantum Entanglement the puzzles take place in rooms where you can move one cube and another cube will mimic that movement. This is the twentieth level of the game, and is set within a dilapidated Test Chamber. Here are the best I found.įirst up, Quantum Entanglement.
