GoNNER is a tough as hell procedurally-generated 2D platformer with roguelike elements, following the largely misunderstood and altruistic Ikk on a journey to cheer up his only friend in this world—a giant landbound whale named Sally. Procerdurally-generated environments, arduous bosses, hidden secrets, multiple endings, and more await Ikk on his journey to make one person happy even if it kills him—which it certainly will.
