Perfected Marginal on Hard.
The notes of this song are.. fast! They caught me off-guard on my first try. But the main killer was the weird combination in the middle of the song. I managed to get past it in one of the tries, and then I made a determination not to screw up for the rest of the song, else I had to go through it again. Fortunately I made it.
As usual, I spent 4 help item chances. This is creeping me out.
Next song: Love List Koushinchuu? on Hard
