Your music becomes a level
Rythmo Bille is a rhythm platformer: a ball jumps from platform to platform, and every platform is a musical note. Land exactly on the beat and you are the one playing the melody.

The idea fits in one sentence, but it changes everything: instead of following a level designed in advance, you play the music you love. The game analyses a song, finds the notes of the melody and turns them into platforms placed exactly when each note should sound. Higher notes sit higher on screen; the faster the notes come, the earlier you have to jump.
