Archives of Alexandria

From the introduction: In Archives of Alexandria, two players inhabit the roles of BiblioTechs, eternal creatures tasked with monitoring the recorded wisdom of our Earth aboard an infinite abstract space vessel called The Alexandria. The escape vessel only works with two keys to ensure the safety or shared demise of the BiblioTechs on the ship, so you must race the spreading virus and traverse the winding extradimensional halls of information to reach your shared goal before you run out of time.
