Passage: Noel Berry (Skytorn) and Matt Thorson (TowerFall) created a prototype of Celeste in four days during a game jam, now named Celeste Classic. The result was a difficult platformer with 30 levels for the Pico-8 fantasy video game console designed for speedrunning and precision reflexes. Kill Screen noted that the game was a departure from Thorson's TowerFall, and had more in common with the game mechanics of his older games and Super Mario Maker work. The developers also took inspiration from difficult, Super Nintendo-era platformers. Berry and Thorson developed the game into a standalone release with over 200 rooms spread between eight chapters. They livestreamed parts of their development process on Twitch. The game was also demoed at the 2016 PAX West Indie Megabooth. Celeste released on Nintendo Switch, PlayStation 4, Xbox One, Windows, Linux and macOS on January 25, 2018. The original Pico-8 prototype is included in the game as an unlockable minigame. The game will eventually receive a limited collector's edition. Thorson stated that he plans to release a set of "farewell levels" for Celeste some time in 2019.
