The Entropy Centre
Cubes that shoot out laser beams or bridges, jump-pads, fans, and conveyor belts that can be reversed to transport objects or yourself: all of these elements mainly serve to obfuscate the same essential process
Not long after waking up in The Entropy Centre’s abandoned lunar base, you arrive at an observation deck, the Earth hanging overhead – for a couple of seconds, at least, before it promptly explodes into smithereens. Your job is to provide energy to the base’s time-travel engine, thus rewinding the Earth to a more stable, pre-exploded state – energy that is, naturally, generated by completing puzzles.
