User blog:Antihero575/Hardest Sonic Game/Level?

Hi, everyone! I was just wondering what you thought was one of the hardest levels in a Sonic game-or one of the hardest Sonic games. For me it'd have to be Security Hall *shudder*shudder* in SA2:B(I was stuck on it for a week and finally I just got a ton of lives and killed myself on purpose after I got two emeralds so it wouldn't reset where they were hidden -_-).
