The Player controls an entity which can create a connection to various creatures.
This Connection is a line on which the heartbeat of the Player travels to the creatures and gives them energy and brings them to follow you. Before this state they are in an unmotivated non-productive trance.
This connection is affected by the distance the Player an the individual creature are seperated by. If closer together the heartbeat gets quicker while beeing further away can even lead to a flatline and thus to the death of the creature.
While following you, the creatures grow older and become slower to a point where they can't walk anymore...
