The game featured combined 3-D graphics, clay animation and video segments. With its unconventional interface, storyline, and characters, the game's peculiarity became its selling point. The characters are largely lifelike in appearance except for their clay-modeled faces, which are often distorted or feature grotesquely exaggerated features. This near-realism, sometimes referred to as the uncanny valley, contributed to the game's ambience of unease and anxiety.
