At Eternity's Hatch

At Eternity's Hatch is a mystery puzzle adventure centred around an evolving time travel system. Stranded at sea aboard a 1950s research vessel in an alternate timeline, you must utilise the ship's time-travel abilities to uncover information, solve puzzles across timelines and alter the past to return home. As the game progresses, you learn the rules governing the time travel system involving multiple timelines and how to use them to your advantage, unlocking new abilities along the way.
