Rhythm Heaven Megamix

Rhythm Heaven Megamix, known as Rhythm Paradise Megamix in PAL regions, Rhythm Tengoku: The Best Plus in Japan, and Rhythm World: The Best Plus in South Korea, is a rhythm game released for the Nintendo 3DS in 2015 in Japan and 2016 elsewhere, and the fourth installment of the  series. It largely consists of games taken from past installments, along with a plurality of new content. As with previous installments of the series, Megamix is a collaboration between Nintendo SPD1 and song producer (otherwise known as Tsunku♂).

While WarioWare and Rhythm Heaven have made occasional references to each other (most prevalent in Game & Wario), mostly due to being developed by the same team, Megamix solidifies the link between the two series by including a set of minigames featuring the cast of the WarioWare series.

Gameplay
Rhythm Heaven Megamix is a rhythm game tasking the player to play through a series of rhythm-based minigames played using the button, the  button, and the. Megamix alteratively offers a tapping control scheme using the, although it does not replicate the more elaborate touch screen motions from the DS Rhythm Heaven. Unlike other rhythm games, the Rhythm Heaven series has a stronger emphasis on testing the player’s sense of rhythm and will often subvert the visual cues during the course of the minigames.

The main story of Megamix is composed of 108 minigames: 78 taken from past installments, and 30 brand new. Several of the returning minigames in the early portion of the game have new graphics and music, and the games from the DS Rhythm Heaven have been reworked to use button inputs rather than the touch screen.
