[diffraction]

00:05:915 (1) till 00:05:915 (1) - feels so hard and overmapped, the song is calm. there is too much movement

00:52:415 (1,2,3) - this might confuse player to wether they are tapping 1/8 or 1/12. you can def give it a bit more spacing since its slower

01:01:914 (1,2,3,4,1,2,3) - i don't really think the drastic increasing svs are fully justified considering what's going on in the song (slightly rising pitch). i'd either lower how much the slider velocity increases (eg. 1 → 1.25 → 1.5 → 2), or just an increase in spacing would be fine.

plus, this exact pattern shows up 4 times, it'd be more interesting if you were to change the patterning up

01:10:859 (1,2,3) - increase spacing to show its slower. the player could read these as fast triples

01:16:165 (1,2,3) - this is quite hard to both play and read, i think it'd be better for it to be more passive and a reverse slider instead

01:17:915 (1) - this whole jump section seem flooded with unnecessary movement while the song remain pretty calm. you should lower the distacing

01:30:581 (1,2,3,4) - i think you should apply new combo to every single one of these to indicate that this is 1/3

(right now it's not particularly clear that they are 1/3s)

01:51:831 (8,1) - you have to be aware of random unwanted spacing changes like this when creating a stream w/ distance snap on lol

(as distance snap actually behaves differently along with changes in slider velocity)

01:58:581 (5) - this slider should end in 01:58:803 - (1/6)

02:06:248 (1,2,3,4,1,2,3,1) - this is pretty cool

02:06:915 (2) - maybe change to wave slider

02:12:915 (3,4,5,6,7,8,9,10) - 02:23:582 (3,4,5,6,7,8,9,10) - for patterns like these, I would use a different degree of rotation to fit the together nicely (currently a triangle and a odd one out) less harsh angles like 72* can work well.

00:05:915 (1) - I would reduce spacing (in both ending and beginning) and reuse the reverse slider in the beginning (like in the ending). As to decrease the difficulty strain of the very calm entry / exit in the map.

01:10:859 (4), 01:16:165 (5), - I would change this to a 1/4 beat slider on the 1/8 ticks right after slider previous because to its more important to follow the melody here, like what you did here 01:21:498 (1).

02:37:248 - the snares are very important in this song, should be mapped

02:14:581 (1) - it'd be a lot more interesting to vary the shapes of the heavy synth sounds here, as the curved sliders don't do it justice and blend too much with the general shapes in this map.

https://osu.ppy.sh/ss/19052413/57e3 is an example of what i mean, though you can pattern it how you want

02:39:081 (1) - should be a 1/3 slider that starts in 02:39:026 -

02:41:748 (1,2) - this sounds more like it should be 1/6 starting on 02:41:692 -

02:44:248 (1) - this kick is heavily undermapped, you could probably use a 1/8 slider and pattern it with 02:44:415 (2,3,4,5,6,7,8,9,10) -

02:44:415 (2,1,1) - these objects sound like they should appear 1/12 earlier (on the pink tick)

02:47:915 (1) - definitely use a straight slider here, it feels a little out of place and disconnected to the upcoming pattern

03:03:248 (2) - kick is half way through this slider, i think it would be better to have the kicks on slider heads and have these play as doubles instead maybe, though up to you

03:04:915 (1,2,3,4,5,6,1,2) - you could definitely get away with increasing the spacing on this by about 1.1x. The notes felt too bunched up during playtesting.

03:05:915 (3,4,5,6,7,8,9,10,11,1) - please pay attention for this pattern, maybe put 25%/50% speed to see what happens there

03:06:498 (7,11) - Maybe consider removing these two notes entirely? I don't really hear anything significant on those beats and the pattern plays just the same if not better without the notes imo

03:10:748 (1,2,3,4,5) - change pattern here to something different, so that it differs from 02:40:581 (1,2,3,4,1,2,3,4) -

03:13:748 (1) - kick on the slider end is a much stronger sound than the synth on the head, you could probably delete 03:14:248 (2) - and just add a reverse on 03:13:748 (1) -

04:01:581 (1) - definitely extend this spinner, it feels a lot more impactful being a longer spinner

04:42:498 (5) - you could argue keeping this note instead of removing it like my other suggestions at 03:06:498 (7,11) - etc to close out the final kiai with that extra intensity, but again I just don't hear any significant beat here
