Snow... i feel your pain. Demyx critical mode is the most unholy thing ever. Especially when he says "come oen skip to the beat". UGH! bad memories are flooding back to me. Dodge roll is my saving grace though and you NA version players dont have it! BAHAHA!
Yeah, that one is scary, especially since the one that follows that line (got you now!) is the stupid homing water path, that you have no choice to reflect.
The worst part was him jumping around and summoning the water around him after each jump, sometimes it seems like he has no intention of stopping, and you really can't interrupt that unless you want to die.
