00:20:444 (20444|2) - Maybe remove this note since 00:19:844 (19844|3,19994|2,20144|0,20294|1,20444|2,20594|0,20744|2,20894|3,21044|2) is currently 9 consecutive 1/2 notes which is somewhat of a guideline violation (especially because of song bpm) Removing it may also provide more emphasis to 00:20:594 (20594|0) since it's a kinda held note
I'm aware that its breaking a guideline. But honestly, I find that the piano and ping noises are really super clear in this section that it would just be weird if I made it any more simple. But since this is a guideline not a rule I wont make any changed because I did provide 1/1 break at places like 00:21:044 (21044|2) - 00:25:844 - so it shouldnt be too stressful for people to hit those notes
I understand your point but this is an "easy" difficulty and i think that's too much even if you provided 1/1 breaks, the beginning of this difficulty is smooth and enjoyable but suddenly there's 9 consecutive notes and some of them are placed on a very awkward way (example: 00:19:844 (19844|3,19994|2,20144|0,20294|1,20444|2,20594|0,20744|2,20894|3,21044|2) - ). So it wouldnt be easy for a player with this skill level, they wont be able to react to patterns like that in my opinion. I like that you reconsider to change this to something easier (and simple), this might not work for you but it can be more enjoyable for the player.
00:31:844 (31844|2,31994|1,32144|3,32294|0,32444|3,32444|2,32594|0,32744|3,32894|1,33044|3,33044|2) - I guess this counts as a chord during a consecutive 1/2 pattern. I'm not really sure how you should handle this but I suggest simplifying 00:32:444 (32444|3,32444|2,32594|0,32744|3,32894|1,33044|2,33044|3) - to only follow the sounds on 00:32:444 (32444|2,32444|3,33044|2,33044|3) -
00:48:344 (48344|3,48344|2) - why is this a double if these 00:50:744 (50744|1) - 00:53:144 (53144|3) - are not? they have the same sound
01:12:344 (72344|2) - You should move this to column 0 in order to form a minijack with 01:12:044 (72044|0). It's for consistency because other similar places had minijacks as well, like: 02:28:844
01:21:344 (81344|2,81794|2) - I personally don't like shields in easies, but that's entirely subjective. if you do decide to fix it you could just switch the locations of 01:21:794 (81794|2,81944|0).
01:44:294 (104294|1) - I understand there's a sound here but there's the same sound on the following white tick and if you change the timings of this as well as the ln before it to that it's more consistent
01:54:194 (114194|3,114344|2,114494|0,114644|1,114794|3,114944|2,115094|1) - Maybe simply this since "Avoid using more than 5 consecutive 1/2 notes." and all. I suggest probably removing 01:54:794 (114794|3,115094|1) -
02:05:444 (125444|3,125444|1,125744|0,125744|2,126044|3,126044|1,126344|2,126344|0,126644|1,126644|3,126944|0,126944|2,127244|3,127244|1,127544|0,127544|3,127844|0,127844|2,128144|3,128144|2,128444|3,128444|0,128744|1,128744|0,129044|1,129044|3,129344|3,129344|2,129644|0,129644|3) - Repeating the same pattern 3 times is way boring, why not mirroring one of them? so you would provide some variety to that part
02:07:544 - Personal suggestion
how about https://osu.ppy.sh/ss/15737178/a2b3 so no need to do stack notes and you can avoid this three stack notes 02:09:044 (129044|3,129344|3,129644|3) - ? feel free to reject~
02:46:994 (166994|1,167144|2) - Optional but, you should ctrl+h in order to keep consistent with 00:51:794 (51794|2,51944|1) -
02:52:394 (172394|2) -
I suggest move to column 1 to make these 1/2s more balanced among four columns. As 00:57:044 is also balanced on four columns.
