[Chained Chaos]

You speeded it up right? >_>"

Right????

Yes and no. He's using Hyperspeed, which is a "cheat" but doesn't really make anything easier. What it does is space out the notes without changing the timing at all -- so you hit the same amount of notes at the same time you normally would, but the notes are spaced out and come at you faster.
