The creators of Celeste, @EXOK have released a small game named "Celeste 64", which they describe as a "small, heartfelt 3D platformer", "created in a week(ish) by the Celeste team to celebrate the game’s sixth anniversary 🍓✨". Windows and Linux versions are available for free on Itch and they say they're working on a Mac build.
