00:09:577 (4) - 01:30:009 (1) - these reverse sliders with more than one reverse might be misleading for newer players. Since these are pretty intense parts of the song you could switch them for two 1/1 sliders, or even use some circles if you prefer (not 100% sure about using 4 circles tho)
00:09:577 (1,2) - https://puu.sh/ILLqj/5f9d23533b.png Because the sliders are pretty close to each other, it could fumble some beginner players who still may be expecting distance spacing. I suggest moving slider 2 slightly upper right to make them not so close. Other one at 01:30:009 (1,2) - is fine because it's spaced more and also because there isn't an object right after it
This 00:10:225 (2,1,2) - pattern is extremely confusing for beginner players because 00:11:198 (2) - is visualy closer to 00:10:225 (2) - compared with 00:10:874 (1) - making it really easy to misread.
Adjust the spacing in this pattern to something like https://osu.ppy.sh/ss/16979795/c00f to avoid misreadings from newer players.
00:16:063 (1,2,3) - etc Can you try something more to show the song here? All other diffs had at least something, but Normal doesn't got anything related to the song.
Since rhythm is out of the question, maybe you could do something in terms of slider shape, or the placement of the sliders to make it stand out a bit?
Quick bit of goofing around got me https://i.imgur.com/nfwqJQ8.jpeg which stands out visually, though maybe do smth better lol
Could copy-paste-rotate 00:16:063 (1) - for 00:16:712 (2) - and arrange it like https://osu.ppy.sh/ss/16994922/1bfb for slightly cleaner visuals
00:26:441 (1,2,3,4,1,2) - and 00:47:198 (1,2,3,4,1,2) - Not really sure how I feel about these. From the first pattern, it looks like you're going for the idea of the curve slider straightening out after each subsequent one but it isn't executed very well with the given space (object placements seem more elongated) whereas the second timestamp the idea is no longer there and the slider design choices less cohesion (Seemingly randomly rotated). I would recommend re-seating these objects to more closely follow a pattern idea/theme
00:48:495 (1) - remove NC, 00:51:090 (3) - add NC
for consistency with 00:26:441 (1,2,3,4,1,2,1,2)
it would probably be better to map these 00:54:982 (1,2,3) - a bit more actively just like you did previously here 00:34:225 (1,2,3,1,2) -
01:07:793 (1,2,3,1,2) - this rhythm should just be the same as what you did previously here 00:57:414 (1,2,3,4,5,6) - tbh. It would represent the repetition better + the rhythm would fit more imo
01:23:523 (3,4) - I think making this one the same as this 01:20:928 (1,2) - would be better too
This 01:08:604 (3,4,1,2,3,1,2) - chain is very dense for the BPM of the song. 7 objects in a row can be extremely straining for newer players.
Break this chain into a simpler rhythm like https://osu.ppy.sh/ss/16979819/b274 to reduce strain in this section.
Since 01:16:712 (4) - is a 1/2 slider to reflect the toms, you could also map 01:16:387 (3) - as a 1/2 slider to passively map the tom on 01:16:550 -
01:21:577 (2) - would be better to ctrl g this and move it out more to make the sliderhead more obvious, cus rn the sliderhead of 2 is further away from 1 than the sliderend of 2 is closer to 1 u feel?
01:22:225 (1,2) - would replace with 1/1 reverse slider + circle, doing six 1/1 sliders in a row 01:20:928 (1,2,1,2,3,4) is kinda bland
This 01:24:820 (1,2,3,4) - pattern is really hard to read because it is not visualy intuitive and can lead to a lot of misreadings.
Adjust this pattern in a more linear way like 01:15:739 (1,2,3,4) - to avoid reading issues from beginner players.
01:26:117 (1,2,3) - 00:05:685 (1,2,3) - could use same rhythms here
also i suggest not to map this 01:26:604 (2) since u dont do the same thing here 01:29:198 (and doing so would make the chain too long)
01:27:414 (1,2,3,4,1,2,3,4,1) - this chain of 1/2 objects is way too difficult for this difficulty and doesn't quite fit this section. It would probably be better if you used the same rhythm you used previously here 00:05:685 - since they are basically the same section, and even if the second one is more intense, I don't think it would cause any contrast problems
01:31:468 (1,2,3,4) - this rhythm sound quite odd to me. Making 01:31:468 (1) - both of these sounds clickable would probably make it more intuitive, leading to a rhythm like this https://i.imgur.com/JhexB7n.png
