i think something is wrong with 01:00:732 (2,3,4) - and similar decisions on that section of the song because:
01:00:732 (2) - is that japanese toy piano
01:00:902 (3) - is a "su" (す)
01:01:073 (4) - is a piano again.
you mapped 2 different things (instrumentals and vocals) in a same sort of a stack with notes that narratively tells that these three sounds are the same: same tool to map (note), same spacing, same rhythm.
i suggest to rather change something to a slider or buff spacing. you decide.
the problem of 01:04:483 (1,2,1,2,1,2) - tho is that it's comically the biggest diffspike and the biggest jumps player will do and this will never appear ever again. this is inconsistent and unnatural, also people will probably miss on that and waste 1 minute of their lives and blame u ofc.
i would suggest to nerf the spacing or buff the spacing of your 01:06:529 (1) - kiai sections.
i think there's no sound to map on 01:20:254 (2) - and so on sections like that. there's no sound. maybe put sliders on first notes?
