Cookie Run Kingdom is a continuation of the lore established in Devsisters' previous title, Cookie Run Ovenbreak. The story in both games follows a group of sentient cookies that have escaped being baked alive in the oven of a group of witches and journey across the world of Earthbread in order to find a paradise for all cookies.
