Two Player
Micro-Row (小さないきもの) is the 4th Rhythm Game in the Two-Player Menu in Rhythm Heaven Fever. It is unlocked after completing the One Player version.

There are now five Microbes in a row, with P1 controlling the blue microbe (second in line) and P2 controlling the orange microbe (fourth in line). All other microbes have slightly different colors as well. At the end of the game, instead of zooming up close to the player's microbe, the camera continues to zoom out until they can no longer be seen.
