Perfected from Y to Y on Extreme.
It took me several tries. This song has a unique double-tap-normal-double-tap note combination, which took me some time to get used to. That’s the only tricky part of the song, besides the closely-packed notes. On my last try, I kinda screwed up badly but somehow managed to keep the combo going, so I used 7 help item chances in the end.. O_o and mostly for that one part.
