Block Universe

cube man is in charge of parallel universes it comes from the fourth dimension, its daily work is to use photons to help people time travel, cube man controls the smooth running between parallel universes, the rules in the cube universe give each person the right to travel through time and space once, and can not return to their own universe after crossing. On this day, because of the input photon anomaly, the photon he used to help people travel through time and space was leaked in the time travel station, making the cavity chaotic and the travel trip seriously wrong; cube man needs to retrieve the lost photon to restore the original appearance and order of the time travel station. On the way to retrieve the leaked photons, it is discovered that the photons are only attached to two-dimensional objects and their time can be arbitrarily regulated. As the cube man solves the puzzle, eventually through the mirror of time saw the truth of the cause of space-time disorder so that the parallel world restored the peace of the past.
