Celeste is a 2D precision platformer that has speedrunning at the core of its design. The two main movement mechanics, jumping and dashing, can be combined in various ways to enable a fast and fluid movement-based speedrun and runners can focus entirely on their movement due to the complete absence of RNG. Categories vary in length, but across all of them there is fast-paced, technical gameplay, risk-reward decision-making, and routing choices that trade off faster speed for increased difficulty. With its simple mechanics and immense skill ceiling, Celeste has something for every speedrunner no matter their experience.
