mods will need to nitpick on this
I think I'm the only one who would check this
Anyways, first things first, I suggest to move 00:16:49 ~ 00:38:51 by 1/4 beat forward.
I noticed this beause when I played the song, I keep getting 100s and 50s.
I checked on the bpm/offset its the same as mine.
So I think the notes placed on the timeline are off, and it is.
Well mostly all the flaws upon checking Insane comes from the notes that are placed on the blue timeline. And I think if they are moved 1/4 beat forward (red OR white timeline) it would sound better.
Try to go through the song and check those notes that are placed on the blue timeline and I'll check it again.
EDIT: Here is the "alittlebitharder" version of mine. If you're not planning to make hard you could make mine the hard version, and rename [James] to hard. Since I think having my own difficulty is too good for me. XD
