while gds have some leniency when it comes to spread, i believe this diff would benefit a lot from some buffing seeing how this diff's densest section is a single 5-plet in 01:13:178 while futsuu uses 1/2 very liberally, making the jump from kantan-futsuu feeling abit larger from the rest of the set.
some places you could add notes to buff:
00:16:263 -
00:31:349 -
00:32:721 -
00:44:892 -
00:46:263 -
00:55:863 -
00:57:235 -
01:01:178 -
01:01:863 -
this kind of takes away most of the targeted emphasis for stronger sounds i want to emphasise so i'd rather keep timeline fairly sparse
