I feel like AR9 is too fast for this song and the visible note density is really low. I think it's not really good for players at this skill level to playing low visible note density as it usually results in reading skills deficiency later on. I've tested and anything between 8 and 8.7 works fine.
8.6OD 8.5 might be a bit too high for the targeted player group. Consider trying out OD8 .
8.200:05:925 (1,2,3) - the pattern here misses the piano notes I think. Usually on the piano the note on the downbeat is played with the left hand then the notes from the first red tick on start on the right hand, so a circle on the downbeat to represent the left hand then the 1/2 sliders to represent the right hand could work out. That's my reasoning for this part.
https://osu.ppy.sh/ss/5093746 try this. It is slightly subjective here.
err... I guess no00:08:925 (1,2,3) - same here. Also subjective.
^00:02:925 (1,2,3) - ^
^00:05:925 (1,2,3) -
^00:12:675 (3) - I think this slider should be broken into 2 notes because 3 4 5 are in the same chord therefore they should have the same pattern.
no00:21:675 (5) - I think the red tick should be mapped , let's try a reverse arrow on the red tick?
https://osu.ppy.sh/ss/5093821 .
it's just the same as 00:14:925 (1) - and 00:17:925 (1,3) - so I guess it's not that problematic to follow00:46:425 (4) - The red tick here should be mapped as well because you try to follow the guitar line with 5.
https://osu.ppy.sh/ss/5093836 ^01:20:925 (1,2,3,4) - There's an extremely interesting synth line going on here but you sort of ignored it. You can map this section a lot better. Try this pattern?
https://osu.ppy.sh/ss/5093859 . It's a star -> square .
I'm not kind of mapper that follow everything on the song just because this is the hardest diff... sorry.01:23:925 (1,2,3,4) - Same here.
^01:32:925 (1,2,3,4) - ^
^01:26:175 (1,2,3,4) - 1 2 3 go with the piano but 4 is actually the cymbal sound. I suggest removing 4 and making 3 a 1/2 slider.
00:26:925 (3) - NC this maybe? To differentiate from 1 2 which follows the drums.
ok00:27:675 (5,6) - If you're following the piano these ticks should be mapped as 1/2 sliders. Like how you did it here : 00:29:925 (1,2,3,4) -
ok ok00:59:175 (8,9) - 9 lands on a weak sound while sliderend of 8 is a piano note so the emphasis here is slightly wrong.
