Celeste 64: Fragments of the Mountain

Celeste 64: Fragments of the Mountain is a 2024 3D platformer video game developed and published by Canadian indie studio Extremely OK Games for Linux, macOS and Microsoft Windows. The game was developed during a week-long game jam, in which it released in celebration of the sixth anniversary of the 2018 video game Celeste. The game released January 29, 2024, acting as semi-sequel to that game and a continuation to its narrative.

The player controls Madeline, the protagonist from the first game, who has returned to Celeste Mountain in order to reunite with Badeline and contemplate overcoming a big step in her life. Many people who worked on Celeste returned for this game, including composer Lena Raine who released a new soundtrack for it. The choice to transform the Celeste formula into 3D gameplay came from investigating a Quake level editor. Fragments of the Mountain received positive reception, with critics praising the game for its difficulty and soundtrack, whilst criticizing the game for its clunky keyboard controls.
