Geometry Dash: Old vs New - Duelo Maestro (no lag)
Another comparison video about a level called "Duelo Maestro". What this level is about is that it is one of the hardest dual levels ever played. This is also a laggy level (only Master Duel) and Nexus played it with no lag (for some reason). This is an Insane or Extreme Demon in Geometry dash. That all I can say about this level, GOODBYE!
