Relax:
00:17:590 (3) - Move down one square.
00:19:002 (4) - Imo end the slider so it ends on this note.
00:26:767 (4) - Remove finish sounds bad.
00:28:708 (2) - Down 2 squares looks randomly places atm.
00:29:590 (4) - Remove finish.
00:32:414 (4) - Kind of sudden slider, I guess it's okay though. Move it up with distance snap though.
00:35:237 (4) - Move right 1.
00:38:061 (4) - Remove finish.
00:40:884 (4) - ^
00:49:002 (x) - Kind of expect a note here, maybe you can extend the previous slider so it hits this note?
00:51:825 (x) - ^
00:54:296 (3) - Remove finish from the end.
00:55:531 (4) - Move this from under the slider so it's visible.
00:55:884 (x) - Note?
01:05:767 (1,2,1,2,1,2,1,2) - Remove the new combo spam here you don't do it anywhere else.
The rhythm was good at the start and end but in the middle of the song it was a little hard to follow due to gaps in the notes, maybe you could use sliders to fill those gaps?
Fuwafuwa:
00:15:825 (6,7) - Bad overlap with the previous notes, move this so its in a different position from where 00:15:119 (4) - was.
00:59:943 (x) - Note?
01:23:765 (2) - Unsnapped
01:26:765 (4) - Unsnapped.
H-boy's lol:
-- Name is something other than "lol" it's a bit too ambiguous.
00:16:355 (1,2,3,4,5) - Might look better if symmetrical.
00:23:237 (5) - New combo to make it easier to see.
00:47:590 (2) - Slow down is unexpected, it doesn't play very well. (Imo make the spacing x0.5 to make it play better)
00:58:267 (9) - Delete? Sounds bad imo.
00:59:590 -- Maybe make this "soft" like the beginning.
01:26:414 (5) - New combo for visibility.
01:27:649 (10) - Return on 1/4?
LK Crazy:
-- Spacing is kind of hard to follow.
00:04:355 (4) - New combo.
00:08:590 (8,9,10,11,12) - Weird jump, maybe place this diagonally from previous note to minimise overlapping.
00:11:767 (8,9,10) - Unintuitive jump.
00:13:178 (5) - Weird jump.
00:14:325 (6,7,8,9) - Bad zig zag stream.
00:21:561 (5,6,7) - Bad stacking move 5 from under the slider.
00:22:355 (2,3,4,5) - Spacing?????
00:28:355 (1,2,3,4,5,6,7,8,9,10,11) - The overlaps in the combo are awful and really hard to see approach circles.
00:31:884 (8,1,2,3) - ??? Its almost impossible to tell whats going on here 2 is hidden.
00:33:737 (6,7) - Stacking like this is extremely hard to read.
00:40:708 (10,11,1) - Confusing.
01:06:031 (6) - Confusing.
01:09:472 (6,7,1) - 7 is confusing.
01:17:061 (1,2,3,4,5,6,7,8,9,10) - Random spacing and stacking.
01:18:825 (4,5,6) - Confusing...
I didn't enjoy this difficulty very much, sorry the spacing is hard to follow the overlaps make the approach circles a nightmare to read, the kiai doesn't help in visibility and it's overmapped...
Well I'll come back and star this when those unsnapped things have been fixed.
