Trivia

 * The level was originally built to be harder than Bloodlust, but, as MindCap predicted, Technical49 has nerfed the level to top 10 difficulty.
 * The level uses the entirety of the song, being one of the few Extreme Demons to do so.
 * In real life, Sigma (Σ,σ,ς) is the eighteenth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 200.
