Released in 2007 for the Nintendo DS, Ontamarama is a unique rhythm game where players use the stylus to tap and slide on colored notes called 'Ontama'. Set on an island, players must save Ontama from an evil demon who seeks to exploit their musical power. Players navigate through various levels, each with their own set of tunes and difficulty settings. The game combines elements of music and action, as players synchronize their stylus movements with the beat of the soundtrack.
