Unutterable is A Single Player Game of Unnamable Cosmic Horror in which you, the prisoner, are pursued inexorably by some nameless and inconceivable horror. You must retrieve and retain keys from five locations in order to escape the twisting and illusory castle you find yourself in, before time runs out or the haunter in the dark catches you for the last time. 

The board represents a strange and ever-changing castle prison. You play movement cards from your hands to collect the keys to escape your place of confinement, but with each move you make, the field draws ever closer..
