# Cadence: reimplementing Geometry Dash 2.2091 in Rust

> Cadence reimplements Geometry Dash 2.2091 in Rust for desktop and browser play using the user's game resources. Its notes record binary analysis, level-data study and runtime traces; comparison tools check physics and camera behavior against the original. The author reports step-by-step position and velocity matches on 135 recorded runs, while the project remains in early development.
