General:
-- Delete .osb.
-- Make the combo colors the same on all diffs?
-- Hmm, song quality sounds kind of bad, can you find a better one? ^_^
-- I think the song title should be "Open Your Heart
-- BPM should be 108.03 Offset 39 (Though it's hard to tell with the mp3 ~)
Easy:
-- I like the blue combo color on this difficulty, maybe use it on the others to?
00:35:584 (4) - New combo.
00:46:413 -- Make kiai start on 00:46:690 (1) - instead.
00:55:297 -- Volume change intentional?
02:44:413 -- Make kiai start at 02:44:413 (1) ?
Normal:
-- Hitsounds too quiet.
00:35:584 (5) - New combo.
00:46:690 -- 01:04:458 ~ Honestly, I don't think the normal whistles suit this section.
00:47:246 (2) - Remove whistle from the slider.
01:25:839 (1) - ^
01:57:768 (1,2) - These normal whistles don't fit.
02:02:211 (1) - ^
02:53:020 (1,2,1,2) - Clustered, can you space these some more?
02:59:961 (1) - Remove whistle.
Nice map, the only thing I didn't like was the Normal whistle. The song is really soft so it sounded strange, I pointed out the places they sounded worse (imo), but you might want to change some of the others to ^_^
Insane:
-- Rename to Hard.
-- Hitsounds are too quiet.
-- I think you should use the "Normal" hitsounds some more ^_^
00:07:681 (2,3) - Spread these out a little, so it is like 00:05:321 (4,5,6) - and the other 1/4's.
00:37:667 (4,1) - Spacing!
00:45:857 (5,6,7,8,9,10) - Confusing, and looks messy. Make this a regular stream?
01:12:512 (1,2,3,4,5,6,7) - Put this in the center of the grid? Looks better imo.
01:46:523 (1,2,3,4,5,6,1,2,3,4,5,1,2,3,4,5) - Consider using some "Normal" hitsounds here.
01:49:994 (2) - This plays weird, maybe place it where the slider ends?
01:51:105 (1) - ^
02:14:982 (3,4,5,6,7) - Spacing. Why are these 1/4's so widely spaced?
02:46:357 (1,2,3) - This feels a little clustered.
Hmm... lots of streams and triples, I'm not sure it suits the song to be honest.
