Celeste is a 2018 platform game designed, directed and written by Maddy Thorson and programmed by Thorson and Noel Berry. It is a fully-fleshed version of the 2016 PICO-8 game of the same name, 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.
Celeste was released worldwide independently on January 25, 2018, on Microsoft Windows, Nintendo Switch, PlayStation 4, Xbox One, macOS, and Linux, followed by a release on Stadia on July 28, 2020. It consists of eight chapters, plus a free DLC chapter titled Farewell released on September 9, 2019. Farewell acts as an epilogue to the main story and adds 100 new screens.
