Celeste is a 2018 platform game designed, directed and written by Maddy Thorson[note 2] and programmed by Thorson and Noel Berry. It is a fully-fleshed version of the 2016 PICO-8 game of the same name,[note 4] which was made in four days solely by Thorson and Berry during a game jam. Set on a fictional version of Mount Celeste, it follows a young woman named Madeline who attempts to climb the mountain, and must face her inner demons in her quest to reach the summit.
