Easy:
-- Some notes are unsnapped by 1ms. (e.g. 00:41:966 (2,3))
00:16:606 (1) - Is the Finish here a mistake? If then, delete plz.
00:41:966 (2,3) - I think the whistle should be at the end of (2), not (3).
00:58:358 (5) - Delete this. I don't think 5 clicks fit in Easy, even the rhythm is 1/1.
02:19:080 (3,4) - Imo to emphasize Finish in (5), I suggest to delete Finishes in these notes.
02:39:531 (4) - Why did you placed at 1/8?
02:42:005 (4) - ^
02:50:008 (1) - Delete Finish? Sounds noisy.
03:06:400 (4) - I think hit sound with Whistle-Clap is better.
Normal:
00:52:173 (3) - I can't agree with a long slider in this kind of part. Instead, place a note at 00:52:173 and make a slider in "Nyan nyan nyan"
00:58:668 (7) - NC?
01:47:843 (1) - The linear here wasn't completely straight. Was that your intention?
02:29:905 (1) - Delete this note. A note right after a spinner will be hard, considering this diff is Normal.
02:29:905 (1,1,1,1) - Combos were too short, and imo starting NCs in downbeat would be better.
03:08:874 (4,5,6) - Make a better triangle.
Tsusoko's Hard:
00:14:132 (4) - Suggest NC. The term is too long to be in one combo.
00:26:812 (1,2,3,4,5,6) - I hope you can place this more far from the previous note. Jumps with 00:26:039 (8,9) will lead to confusion in playing.
01:00:523 (1) - Delete Whistle at the end?
01:59:905 (1) - ^
01:12:276 (3) - Place at (336,280)? I think this kind of way will be better than a stack.
01:21:477 (3) - Delete please. 1/4 doesn't fit imo.
01:40:884 - Add a note as well as 00:41:503 (1)
01:47:843 (1) - Consider a shape like this. This will be better with flow, and also can avoid contacting with (5).
02:23:410 (4,5,6) - Instead of a rhythm like this, two 1/2 sliders will fit the song better.
02:27:740 (1) - This spin is too long. Divide into 2 spins. Suggesting to end the first spin at 02:29:596, and the second spinner 02:30:214 - 02:32:688.
02:33:925 (1,2,3) - Actually, not a bad idea to anti-jump. But, since this is the only one, I didn't think it's nice in the map.
03:11:967 (2) - Delete Whistle?
Hinely's Nyaaan:
-- Volume sounded loud in some parts.
00:38:152 (2) - Instead stacking, place at (112,96)?
01:01:039 (1,2) - I expect these notes somewhere right of the screen.
01:01:168 (1) - Umm...... Starting at 01:01:245 will be better ;_;
01:15:884 (10) - Delete this note? I can't hear anything from the song.
01:33:307 (1) - End at 01:35:059
02:00:111 (2) - I don't think this is a nice spacing.
02:00:420 (4) - Also here.. ^
02:50:034 (1) - Starting at 02:50:111 will be better..
02:56:503 (3) - Place at (304,72)?
03:12:379 (1) - Add Whistle?
