GoNNER

"Gonner is a hard-hitting, procedurally generated 2D platformer with roguelike elements. You follow the largely misunderstood and altruistic Ikk on his journey to cheer up his only friend in this world - a giant land-bound whale named Sally - by searching for the right gem in the deep and dark places nearby. With Death as his mentor, who provides him with a variety of abilities and an entire arsenal, Ikk traverses an ever-changing land full of unwieldy creatures that neither appreciate his intrusion nor his friend Sally. Different environments, difficult bosses, hidden secrets, multiple endings and much more await Ikk on his journey to make one person happy, even if he gets killed in the process - and he certainly will."
