Lockstep

 Lockstep is the twenty-seventh game in Rhythm Heaven. In this game, you must tap to keep the beat and then make transitions to the offbeats. If you get a perfect, you'll earn the song for Lockstep. Lockstep appears again later in the game with its sequel, Lockstep 2.

Gameplay
The step-switchers will first begin stepping in beat after the clock signal in the background reaches its fourth tick. The player must step consistently in this same beat until one of the step-switchers signals to step in offbeat to the rhythm. The rhythm will keep switching on and offbeat during the game when signaled.

Controls

 * Tap = Stepping in place

Trivia

 * In reality, the word "Lockstep" refers to single-file marching.
