Geometry Dash is a rhythm-based platformer created by Swedish developer Robert Topala (RobTop) and released in 2013. Players guide a square (or other icons) through levels filled with spikes, saws, and gaps, timing jumps and movements to an energetic electronic soundtrack. Despite simple controls — typically a single-button jump — the game’s precision timing, fast pace, and unforgiving obstacles have made it a notable phenomenon in indie mobile and PC gaming.
