Celeste is a 2D platformer developed and published digitally by Matt Makes Games for Mac, PC, Xbox One, Playstation 4 and Nintendo Switch on January 25th, 2018. The game is a follow-up to Celeste Classic or "Pico-8" released in 2015 and built in four days.
The game follows Madeline as she attempts to climb a giant mountain called Celeste Mountain. On the way she meets many different characters and her reason for climbing the moutain gets gradually revealed.
The story features Madeline, who is trying to make the summit of a huge, far off mountain called Celeste Mountain.
On her way up she meets various, quirky characters, among them Theo, a fellow climber and hobby photographer, a mysterious and mean old woman, an unnamed shadow clone of herself, representing her darker (or as the clone puts it, more pragmatic) side and the ghost of a run down celestial resort hotel, Mr. Oshiro.
Along the way Madeline's reasons for trying to reach the summit are revealed as well as her struggle with anxiety and panic attacks.
The goal of the game is to climb the moutain, which can be done by clearing one short screen after another while avoiding various obstacles like sawblades, pitfalls or corruption.
The game features multiple routes to finish a level (made up of multiple short screens), collectibles in the form of strawberries and optional "B-Side" levels, which are remixed version of the regular levels, with remixed music and a hard difficulty spike.
Players control Madeline, who can jump, dash, grab on to and climb walls. The jump and dash only recharge after hitting the ground (there are variations on this, with some obstacles or objects recharging the dash as well) and grabbing and climbing is limited by stamina.
Hitting an enemy, an obstacle or falling into a pit results in an instant death, accompanied by a Mega Man style explosion, requiring the player to start the level over again. Respawns happen instantaneously.
