Geometry Dash

The difficulty categories in geometry dash are legendary, ranging from Easy to Demon. Demon levels themselves are subdivided into Easy Demon, Medium Demon, Hard Demon, Insane Demon, and the dreaded Extreme Demon. Beating these levels requires days or even weeks of practice, and players often livestream or document their progress. The pride of completing an Extreme Demon is enormous, often shared in the form of YouTube uploads or community shout-outs.
