In The Eternal Cylinder, players control a herd of adorable creatures called Trebhums and must explore a strange alien world filled with exotic lifeforms, surreal environments, and the constant threat of the Cylinder, a gargantuan rolling structure of ancient origin which crushes everything in its path. This unique ecosystem is a massive, procedurally generated land with unique animal AI, real-time world destruction, and organic exploration and puzzle design to create emergent gameplay that ensures no two playthroughs are ever the same.
