Celeste-style 2D precision platformer movement — momentum running, coyote time, variable jumps, dash, wall jump/slide, climb stamina, pixel corner correction.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Celeste-Style Momentum Platforming (Movement System) ## Outcome A 2D character controller for Summer Engine that reproduces the tuning architecture and forgiveness mechanics of Celeste's player movement: momentum-based running with distinct ground/air acceleration, variable-height jumping with coyote time, a multi-directional dash with cooldown and residual speed, wall interaction (jump, slide, climb with stamina), and pixel-scale corner corrections that make near-miss inputs succeed instead of fail. ## When to Use - Building a precision 2D platformer in Summer Engine where movement feel is the core gameplay. - Porting or prototyping Celeste-style mechanics (dash, wall jump, climb stamina). - Tuning an existing platformer controller that feels "unfair" or unresponsive — the forgiveness systems below are the primary fix. Do not use for: 3D character controllers, physics-driven (RigidBody) movement, or games where floaty/arcade jump physics are desired over momentum precision. ## Core Principle …

How to install
mdr add summerengine/summer/celeste-momentum-platforming@sha256:a3a78ffbc636985bThe line at the top of this page pins the label git:20261010.4ade947, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
