Hard00:09:534 (9) - balance the new combos here. NC here
00:11:352 (1) - remove NC
00:13:170 (3) - NC
00:14:988 (1) - remove NC
00:16:807 (5) - NC here instead of 00:17:943 (1)
00:17:943 (1) - the music here doesn't start a new phrase or differentiates itself from 00:16:807 (5) - there shouldn't be such a jump here after the slider. You should place it at the end of 00:16:807 (5) where it would be much better suited with the song
00:20:670 (7) - NC here instead of 00:20:898 (1)
00:21:352 (2,3,4,5) - make the spacing between them equal, like this:
00:23:625 (8) - this part is silent, remove the circle
00:42:112 (1,2,3) - differentiate the spacing between them. The time between hitting them is very different. 00:42:112 (1,2) are only 1/2 beat apart yet they are the same spacing as 00:42:769 (2,3) which are 1 beat apart. Place 00:42:769 (2) closer to 00:42:112 (1) - don't make spacing such that it fits a pattern but ignores timing differences. You shape the map to the song, not the song to the map. You should not ignore spacing for the sake of patterns, it doesn't play well.
00:54:496 (1) - remove new combo
00:55:781 (3) - NC
01:08:424 (2) - space it further away from 01:07:996 (1) they are too close to each other for 1/2 beats
01:08:638 (3) - ^
01:10:567 (4) - the crucial beat is on the end of this slider, which feels weak, which should not be the case, you need something to start at 01:10:781 so you can click on it, emphasizing it.
01:15:710 (1) - remove NC
01:16:353 (4) - NC
01:17:853 (7,8) - bad spacing, place them further apart
01:19:353 (5,6,7,1,2,3,4,5,6,7,8) - this flow is honestly quite terrible, it doesn't play well
01:28:138 (1,2,3) - all the crucial beats are on the end of the sliders, you should allow players to click on something during the white ticks, this just weakens the rhythm
01:30:067 - 01:35:210 - reduce the volume of this part
02:07:567 (1,2,3,4,5,6,7) - ^ all the emphasis and increasing volume of the song is lost
02:24:924 (1,2,3,4,5) - irregular spacing is ugly and not necessary here
02:33:496 (5,6,7,8) - not even stacked well
02:36:067 (4,5) - space them further apart
02:36:067 (4,5) - not even stacked well
02:43:567 (5,6) - this should be spaced further from 02:43:138 (2,3,4) - the music grows loud here as it reaches a peak, them should be some sort of decent spacing or jump to show it
03:52:996 (6,7,11) - not even stacked well
03:55:781 (1) - finish on start of slider
The spacing and positioning looks really bad and not well-thought. Most of the time, the objects are really too close together, especially this being the Hard. The spacing just changes too often and too random for it to have any such purpose in the map. The changes just no reason being there and there is no regard to proper spacing, as more often than not, the objects are placed there to fit some sort of pattern, which sometimes are really weird as well. New phrases, new verse, an increase or decrease in vocal or music volume, a peak in the song. Such parts of the music would then deserve some sort of spacing change. Most of the time, a constant decent spacing would suit the map. The direction of play goes left right center, everywhere. Just look at 00:51:924 (3,4,1,2,3,4,5,6,1,2) - one moment you are going one direction. But the next you change your direction totally without warning or reasoning. What this needs is better flow, which comes about with better positioning, where play would be much better. Cut-backs and change in direction is fine, but when placed right and not all the time too. This Hard is currently in quite a mess and unpolished state. Rhythm is honestly decent enough, but the positioning is just not good.
I shall not look further on at the other difficulties, but they have similar issues with movement, especially with being all cramped and squashed together due to the lack of spacing between notes. Insane is in a confused mess with the sudden stacks and short distance spacing between 1/2 and 1 beat rhythms and lack of much differentiation between the timing differences.
Work on them and improve on this mapset. There is much to work upon but things can be much clearer in the future.
I wish you good luck
