Control a herd of adorable creatures called Trebhums and 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. Your Trebhums begin their journey at the bottom of the natural food chain. But they can mutate and evolve new physical attributes and abilities by eating various flora and fauna. Discover and adapt dozens of mutations, including new traversal skills like flying and swimming to reach new areas, and new senses to help overcome puzzles, challenges and dangers. The Eternal Cylinder offers an unique ecosystem where creature AI, real-time world destruction, organic exploration and puzzle design all combine to deliver a unforgettable gameplay experience.
