Take control of your spirit in limbo as you via against other players to be reborn.
Players take turn trying to achieve their goals before they run out of moves and their turn ends. When that happens, another player takes control of the character and tries to complete their goals. It's a battle of wills as you try to outsmart your alter egos, and make sure you are the one reborn from the train station of limbo.
Try and save your species from extinction by building up a chain of locations to migrate to your new breeding grounds. But beware of predators, natural disasters and other species trying to save themselves.
