Hi there. m4m request
Note that whatever I say is my own opinion so you do not have to follow everything I say.
Easy
1) 00:07:787 (1,2,3,4,1) - notes 2 and 4 are not on the same y-coordinate and I assume you wanted them to have the same y-coordinate. Either shift 00:09:409 (2) up to (280, 308) or shift 00:10:058 (4) - down to (176,308), whichever one works best for you.
2) 00:20:760 (1,2,3) - I noticed that by the way you placed the notes, you wanted to have a triangle shape between them, but currently the way you placed them, you can notice the triangle shape is irregular as shown in the 1st image https://osu.ppy.sh/ss/5259854
Try and change it so it looks like this: https://osu.ppy.sh/ss/5259868, you can try and refine it further if possible.
Other than that it seems fine.
Normal
1) 00:02:598 (1,2,3) - visually the distance between 1 and 2 looks a lot larger (1.03x) compared to 2 and 3 (0.95x) please fix that as it does not look good and may trip some people up.
2) 00:06:166 (3,1,2) - Forgive me if I am wrong but I assume you wanted to have the pattern look like this? https://osu.ppy.sh/ss/5260005. If not then ignore this point but if you did want it to look like that, then shift 2 to (348,39)
3) 00:30:490 (4,1,2) - Again the triangle pattern you are trying to achieve looks uneven; the gap between the end of 4 and 1 is different compared the end of 4 and 2, as well as between notes 1 and 2. Try and fix it so it looks like this. https://osu.ppy.sh/ss/5260048
4) 00:32:112 (4,5) - Yes I am being very anal here, but the sliders are not parallel. :S
Waji's Advanced
1) 00:44:112 (3,4) - They are not aligned, ie. they are not aligned on the same y coordinate. Copy 3 and press ctrl+h so then they are aligned properly.
Not much else to say
zzz's hard
1) 00:02:760 (2,1) - These sliders are not on the same x-coordinate (Yes I am being very very very very anal, but that is what I have to do in order to polish a difficulty). Shift either slider 1 a pixel to the left, or slider 2 a pixel to the right.
Applies to 00:06:814 (2,3) -
Anything that I am saying is just mostly about polishing. There is not much wrong in terms of rhyhtm and stuff. The map is unique in the sense that you use a lot of horizontal and vertical sliders, and since not many maps do that anymore, it does feel unique in that sense.
2) 00:51:247 (2,3,4,5) - 3 and 4 are not on the same x-coordinate and 2 and 5 are not on the same x-coordinate as well. Since everything is neatly done throught the map, this sticks out like a sore thumb imo.
3) 00:54:166 (4) - Why not have the shape be symmetrical.
Mk's Light Hard
1) 00:15:571 (1,2,3) - Because 2 and 3 are stacked, it affects the distance between 1 and 2; they are overlapping and it does not look good. Just move it away like so: https://osu.ppy.sh/ss/5260307
2) 00:20:760 (1) - If you ctrl+g this slider you can see that the slider is not even (but just by a bit). If you want to fix it then go ahead.
3) 00:48:652 (4) - Refine 4 a bit more so it looks like: https://osu.ppy.sh/ss/5260394
4) 00:54:652 (1) - Split this into 2 notes so because as it is right now, the slider ends on a strong beat and strong beats should be clickable. Alternatively, you could swap 00:54:490 (8,1) around and get the same result.
5) 01:15:247 (2) - Yeah. The slider is not symmetrical. Please fix that as it would make the whole beatmap look a lot better.
Kitty's Insane
1) 00:06:490 (1) - The slider is not even imo. Refine it so it looks like this: https://osu.ppy.sh/ss/5260562
2) 00:41:517 Note how at this part onwards the music and vocals feel a bit slower and calmer? I was thinking to reflect that, lower the SV multiplier to 0.8/0.85x.
Frey's Lunatic
It is fine I guess.
Final thoughts
Since this map seems to have a lot of mods posted, the rhythm and stuff is solid, so I decided to focus my mod on polishing the difficulties and noting down things that were overlooked, hence the reason why I was being very anal with certain things.
Good luck.
