[Heroine]
You mapped different instruments in the song. The problem with that is that the switches between these instruments are not predictable which concludes that the players get confused which instrument they're playing to and think that the objects don't follow the music. In some parts of the map I had some problems figuring out to which instrument you mapped, even in the editor. Also there are some overmapping issues and comboing issues of which I will only point out these that don't play well. Unfortunately I can't help you with hitsounding because I'm not experienced with that.
First example of the problem mentioned above: 00:06:546 (2,3) - Replace these with a circle - slider - circle pattern
00:13:403 - The pause doesn't make sense rhythmically looking at how you placed the objects before. I suggest you to add a circle
00:19:746 (1) - Spinner doesn't fit for the same reason
00:23:688 (6) - The slider end is on a new beat. This should be emphasized by playing a clickable obejct. Switch the slider to two circles
00:24:031 (1,2,1,2,1,2) - These sliders might come unexpected because you didn't map this instrument before. Make them less spaced and give them more linear flow so you don't have to snap to each one
00:25:060 (1) - ^
00:25:403 (2,3,4) - Overmapped and doesn't suit the rhythm at all, delete the note on the blue tick and change it to a jump
00:30:546 (1,2,3) - ^
00:31:917 (7,1,2,3,4) - This rhythm also doesn't fit because there's an emphasized note on the 7. You might want to change it to a rhythm like slider - circle - circle - slider - cirlce
00:33:460 (5,1) - The 5 is also a heavy emphasized note which actually ends where the current 1 starts change it to slider - circle
00:34:146 (4,5) - A slider would fit more here
00:38:946 (2) - A circle would make more sense here
00:39:974 (1) - ^
00:44:774 (2,3,4) - Overmapped and doesn't suit the rhythm at all, delete the note on the blue tick and change it to a jump
00:45:631 (2,3,4) - ^
About here I lost about an hour of modding progress so please understand if I don't explain everything in depth.
00:46:146 (5,1,2,3,4) - Also doesn't fit and is overmapped, delete the notes on the blue tick and change it to a circle - slider - circle pattern
00:48:546 (2,3) - A slider - circle pattern would make more sense
00:54:717 - This gap doesn't fit because you mapped these instruments before, add a circle
00:55:060 (2) - Shorten this slider and add a circle at the current end of the slider to emphasize the start of the new beat
01:00:888 (1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3) - Overmap heaven, delete everything that starts or end on a blue tick. Accelerating jumps would nicely fit here
01:04:917 (1) - Why is there even a spinner? It would make more sense to just map the vocals here
01:06:374 (2) - A 1/1 slider would fit really nicely
01:07:746 (5) - Change this to a reverse slider or add a new circle here 01:08:088
01:08:260 (1,2) - This change of playing to different instruments is really unexpected, delete these and add a circle - slider pattern here 01:08:603
01:10:488 (1) - Shorten this slider by 1/2 and add a circle at the current end to emphasize the vocals
01:11:517 (3) - Shorten this slider by 1/4 and add a circle at the current end to emphasize the vocals and to keep consistent
01:14:603 (3) - Changing this to a reverse slider would fit pretty good
01:16:660 (5) - Change this to two circles to keep the following two circles consistent
01:20:088 (3) - Shorten this slider by 1/4 or 1/2 and add circle at the current end to emphasize the vocals
01:20:946 (1,2,3,4,5) - Overmapped, delete the notes on the blue tick and change it to two jumps
01:30:374 (5,6,7,8) - If you really want overmapped streams, let the triplet start where the 5 is to keep at least a bit rhythmically logical and delete the current 7
01:30:888 (1) - Change this to two circles to emphasize the start of the new beat
01:34:317 (3) - Doesn't follow anything, shorten it by 1/2 and let it start 1/2 later and add a circle at the current start
01:43:060 (4) - In my opinion these vocal parts are that important that a reverse slider doesn't emphasize them enough, change it to three circles
01:43:746 (6) - ^
01:44:603 (1) - Let this slider start 1/2 later and add a circle at the current start of the slider
01:44:946 (1) - Change this to a circle that is here 01:45:117
02:05:174 (2,3,4) - Overmapped, delete the note on the blue tick and change it to a jump
02:07:917 (1,2) - Let these sliders start 1/2 later and a a circle at the start
02:10:488 (2) - A single circle would fit better
02:13:917 (2,3,4) - Overmapped, delete the note on the blue tick and change it to a jump
02:16:574 (1,2) - ^
02:16:917 (1,2) - ^
02:17:260 (1,2) - ^
02:25:403 (1,2,3,4,1,2,1,2) - ^, just add jumps
02:27:974 (1) - Much more spacing to emphasize this properly
02:30:031 (1,2,1,2,3,4,1,2,3,1,1,2,3,4,1,2,3,4,5,1) - There are no notes on the blue ticks yet to overmap even reverse sliders of which the notes don't even have to be clicked which adds overmapped hitsounds, just do normal jumps
02:35:517 (2) - A 1/1 slider would fit nicely instead
02:36:717 (4) - Change it to a reverse slider to emphasize all of the vocals
02:37:917 (1) - Why do you suddenly change to not mapping the vocals, just keep mapping to them because it confuses the players make a circle - slider - circle pattern starting here 02:37:746
02:38:946 (4) - It would be much more nice if you made this a slider and deleted this note 02:39:288 (1)
02:48:888 (5) - Shorten it by 1/2 and add a circle at the current end
02:49:574 (2) - Make this slider start 1/2 later and add a circle at the current start
02:49:917 (3,4,5) - Just do 2 jumps instead
03:00:546 (4,5,6,1,2,3) - Overmapped, delete the notes on the blue tick and change it to a slider
03:01:574 (5) - Overmapped, delete the note on the blue tick and change it to a slider
03:03:288 (4,5,6) - ^
03:09:117 (3) - ^
03:11:517 (1,1) - ^
03:13:231 (3,4,5,6,1) - ^
03:44:774 (5) - ^
03:45:803 (4,5,6,7,8,9) - ^
03:50:431 (3,4,5) - ^, make them normal jumps
03:54:031 (5) - ^, make it a normal slider
03:54:888 (3) - ^ this is ridiculous
03:55:574 (6) - Make this slider start 1/2 later and add a circle at the current start
03:57:460 (1,2,3) - Overmapped, delete the note on the blue tick and change it to a jump
03:57:631 (3) - Change this slider to two circles to emphasize the start of the new beat
03:58:146 (5,6,7) - overmapped + ^
04:00:203 (9) - Shorten the slider by 1/2 and add a circle at the current end
04:00:717 (1,2) - Change this to a circle - slider pattern
04:01:746 (4,5,6) - Overmapped, delete the note on the blue tick and change it to a slider
04:06:888 (6,7,8) - ^
04:07:231 (1) - Change it so there's a circle at the start of the new beat to emphasize it
04:10:403 (3,4) - Overmapped, delete the note on the blue tick and change it to a jump
04:14:260 (5,6,7) - ^
04:14:774 (2,3,4) - ^
04:15:974 (1) - ^
04:17:517 (2,3,4) - ^
04:19:060 (6,7,8) - ^
04:31:231 (5) - ^
04:42:546 (1,2,3) - ^
04:43:231 (5,6,7) - ^
05:09:374 (2) - This doesn't make much sense, make it start 1/4 earlier if you really want this 1/4 slider
05:10:831 (2) - Shorten this slider by 1/4 and make it start 1/4 later
You have got a massive problem with the comboing, just go with a new combo every 4 beats regurarly
I hope this helped a bit. I might add some object placement issues later.
