Supersonic Wii is a music rhythm game where the player needs to hit buttons in sync with the music being played. Based on the gameplay of Amplitude (and its DS homebrew sibling, AmplituDS), and equipped with all-new Wintery stages, you play one part of the song at a time (focus on one instrument at a time, for example drums) until you’ve played it enough to continue on and try another. The music for each instrument track only plays if you are successful at playing the pattern.
