HarmoKnight

HarmoKnight (Rhythm Hunter: HarmoKnight in Japan) is a rhythm platformer game developed by Game Freak and published by Nintendo for the Nintendo 3DS' Nintendo eShop. When the musical planet known as Harmonia suddenly comes under attack by evil monsters known as Noizoids, it is up to Tempo to beat the Noizoids and restore order to Harmonia.

The game follows Tempo as he travels through scrolling levels trying to gather as many notes as possible, either found throughout the level or earned by hitting enemies and objects. Actions correspond with the rhythm of the music and at the end of each stage the player will earn a grade based on how many notes they gathered.
