Game Freak, the folks behind Pocket Monsters, are working on a new download title for the 3DS. It's called Rhythm Hunter: HarmoKnight. It's a platforming game meets rhythm game.
HarmoKnight uses "attack" and "jump" to clear each stage. To take down enemies, it uses a timing mechanic that seems similar to what you'd see in a music game.
Each of the in-game worlds are based on music genres and shaped like instruments: So there's "Marching Hills", "Rock Range", "Calypso Beach". The platforming can get fast and furious—which should please both fans of platformers and those who like rhythm games. No word on a Western release yet, but cross your fingers!
