Every game, with all its enemies and doors and health bars and platforms, has a set pace. A pace in how they move, when they move, how fast they move. And that pace, the pace of everything on screen, dictates the pace that the player can plan out their moves and it dictates the window that the player has to perform their plan. But when the pace of everything on the screen is rhythmic, meaning that the pacing matches a particular interval, is matched by the rhythm of the player to plan and perform within the window that the game gives then a sort of harmonic resonance can develop between the player and the game, and that can be a wonderful feeling to have.
