Deadlocked was introduced with Geometry Dash Update 2.0 in 2015 as an official Demon difficulty level created by developer RobTop. Its soundtrack was composed by Canadian electronic artist F-777, whose fast paced dance style became closely associated with the game through several levels. Because Deadlocked is one of the hardest official stages, its music developed a reputation separate from the game on YouTube, streaming clips and level creator projects. Players and editors still reuse the track to signal extreme difficulty, precision and nonstop momentum.
