Rhythm game with a custom audio engine
Rockerz
Frame-accurate audio–visual synchronisation and a chart parser covering the full range of Guitar Hero and Clone Hero formats. Hard real-time correctness, zero tolerance for drift.

A rhythm game lives or dies on one number: the offset between the note you see and the note you hear. There is no acceptable drift — a few milliseconds is the difference between a game that feels tight and one that feels broken, and the error accumulates over a four-minute song.
I built the chart parser and import pipeline covering the full range of Guitar Hero and Clone Hero formats, and the engine that keeps audio and video locked together for the length of a track.
On top of that sit the systems that make it a game rather than a metronome: star power, character abilities, backgrounds that react to how well you are playing.
