Algorithm

A kalimba is a thumb-plucked instrument with 17 tines; the game has 4 lanes. The algorithm parses the song’s MIDI data and fits it into 4 lanes while keeping how it plays. Tap each step.

Physics Simulation

A 3D marble run built with Three.js. The song’s MIDI spawns one marble per note; Rapier (Rust/WASM physics) simulates gravity, collisions, and restitution so each lands on its tine on the beat.
