Genjin Cottsu — About this game
Cottsu’s island has lost its music, and the young percussionist seeks six legendary instruments to restore it. Travel through six side-scrolling stages, punch obstacles and collect musical notes while jumping across the terrain. Rhythm masters test your timing in repeating A/B patterns, with a separate practice mode for learning their phrases. The adventure alternates platform movement with listening and response, making a steady beat part of the route forward. Try the rhythm practice mode first and select a comfortable level. Listen to the master’s phrase and answer with A/B at the same tempo. Then start the main adventure, using B jumps and A attacks to collect notes through the first stage.
