Mantis Shuffle is a rhythmically interactive game that rewards the player for fast reflexes and matching the music. The goal is to press the appropriate symbol (and to not hit the step mines) as the symbol crosses along the target region. The more accurate of a timing the player has, the greater the player is awarded in both points and amount that the success gauge is filled. Receiving a low enough rating or missing the symbol entirely will result in a decrease in the succeess gauge. The goal is to reach the end of a song with the gauge filled as much as possible and as high of a score as possible. If the success gauge fully depletes than the player (or CPU) will be eliminated and fail the song.
