Your green lines are unsnapped. When you change the BPM or the offset, make sure to fix your green lines afterwards.

HardMy main issue with this difficulty is your choose of a really low distance snap compared to a pretty swift slider velocity. It makes objects that appear after sliders play awkwardly. You can counter this by having more jumps or a larger spacing after certain sliders and to avoid certain patterns which I cover in the mod. If you map your other difficulties similar to the Hard, my mod post will probably be just as large for each difficulty, so make sure you pick a nice solid flowing distance snap that complements the slider velocity you choose in the future.
The secondary issue I had is the mp3 sounds like garbage compared to the hitsounds. Increasing the volume of the mp3 would be an improvement.
The third issue I had is the hitsounds themselves. After awhile, this song gets on my nerves. Some coin placement hitsounds are weird, although I didn't really mention it in the mod. Your choice for long sliders just spams the annoying slider tick sound. Also some things weren't mapped to the proper beat and so they didn't sound right.
02:24:432 (1) - Unsnapped circle.
02:45:535 (6) - Unsnapped slider (start).
03:27:535 (2) - Unsnapped slider (start).
03:28:156 (1) - Unsnapped slider (start).00:39:741 (3,4) - Please space correctly. Although you should have no reason to have anti-jumps/spacing in this map, you should avoid doing it when one or more of your objects isn't on the right tick/ there is an odd gap between the notes.
00:43:051 (1,2,3,4) - Are you manually stacking? I think it looks better if you just stack these normally. It will change the spacing going into the next combo. Adjust for that. If you must manual stack, at least make sure all the stacks are stacking in the same direction.
00:44:706 (1,2) - The spacing difference here is different than the other stacks in this combo. (Testplay to see the difference)
00:47:603 (3,4) - It's consider poor mapping to change the spacing in random ways. If you're changing the snap to change the flow, then it's more acceptable, but when it just seems like you changed the spacing because it fit a pattern, then it seems sloppy. It doesn't play bad, and it doesn't look that bad, but overall you should go for consistent spacing over inconsistent spacing, especially within the same combo. you don't need to change since it works, but consider changing the shape of the slider.
http://osu.ppy.sh/ss/547694 < the slider on the right is much nicer to look at.
00:58:362 (5) - sounds weird with your customs. If you can get it to work, then just a hitcircle here 00:58:568 - works.
01:01:879 (4,5) - Such cramped flow. I think it would be nicer if the spacing was increased here for a jump. It would allow you to bring the slider closer to the center of the screen.
01:02:293 (5,1,2) - I think this would be better if there was more of a slanted transition here.
http://osu.ppy.sh/ss/54773701:03:741 (2,3,4) - Position so that the slider curves wrap around the start of the slider, for a blanket. have the sliders blanket each other.
http://osu.ppy.sh/ss/54774101:05:603 (5) - Have this blanket the end of the previous slider.
01:29:396 -
Kiai needs to be snapped01:30:224 (1,2) - Sounds weird and offbeat. It's not offbeat but it sounds like it, because of how you mapped it. I came up with an alternative that is much cleaner. It still sounds weird due to the custom slider slide though.
http://osu.ppy.sh/ss/547751 <sounds better. Spacing here 01:31:465 (3,1) - isn't that important, you don't need to follow distance snap. You probably shouldn't.
01:34:155 (1,2) - ^ same case, distance snap doesn't need to be followed here, but you may want to keep this.
01:38:707 - Plays better with a note here.
01:39:741 (2,3) - What is this annoying sound.
01:42:638 (1,2,3,4,1,2,3) - I really don't like this hitsounding. It's annoying.
01:45:534 (3,1,2,3) - Curve can be improved.
01:45:948 (1) - x 395 y 200
01:46:362 (2) - x 412 y 121
01:46:775 (3) - x 379 y 48
01:49:672 - Add note?
01:51:534 (1) - I would prefer a more normal looking slider like a U shape or a curve. also please do something about that annoying slider tick sound.
02:02:500 (3) - Next combo should start here. also try to make the curve here 02:02:086 (2,3,1,2,3) - better. (Fix the angles of the curve)
http://osu.ppy.sh/ss/547775 This should be good for now.
02:03:741 (4) - I would change the combo here. I might consider increasing the snap for the slider transition. What do you think?
02:09:120 (1,2) - Don't go over 1.0 snap. Players aren't going to expect this. 1.0 is fine for this type of transition.
02:10:982 (2,3) - This type of curve doesn't look good in the transition you're trying to do. I suggest doing this.
http://osu.ppy.sh/ss/54778002:14:293 (2,3,4,5) - Please move to white ticks, it will play better.
02:19:879 (1,2,3,4) - Curve could be made better. Also it's not recommended to use large sliders that are randomly shaped. Consider including a slider theme to the shape. What I mean by this is that it should follow the sound or exhibit some form. The flat part doesn't fit the music for example. I really can't help you with slider design.
02:22:776 (1,2,3,4,1,2,3,4) - Flows poorly. The spacing for the notes is much slower than the speed of the sliders. It's more noticeable when you go alternate between notes and sliders. Timeline doesn't sound right to me. This sounds like the more stronger beat IMO.
http://osu.ppy.sh/ss/54779102:25:258 (4,1,2) - Jump here?
02:28:569 (4) - Should be shaped similar to 3. There's no sense changing the slider shape.
02:43:258 (2,3,4,1) - You should keep curving around the spiral here.
02:43:879 (1,2) - Sounds out of place and I didn't expect it.
02:45:121 (1,2) - ^ (the beat isn't 1/1, it's a series of doubles)
http://osu.ppy.sh/ss/547802 <Timeline
02:48:431 (3,1) - 0.5 is too close here. Increase the spacing.
02:54:431 (2,3) - spacing is too close. It should be 1.0 because you lead players to assume these parts are going to be entirely 1,1 when you mapped 02:47:189 (1,2,3) -. While you're at it 02:55:052 (3,4,1) - this should be spaced larger too.
03:01:258 (3) - Strange slider- do something else? (consider ending on the white tick)
03:05:396 (5) - Next combo should start here.
03:06:638 - Add note and make a curve here
03:07:052 (1) - Maybe this would be better with more symmetry.
03:15:121 (1,2) - Use a symmetrical pattern?
03:16:362 (1,2,3,4) - Curve here does not really fit the previous pattern. It just seems like it flattens out for no reason.
03:20:293 (1) - Such an annoying slider.
03:36:845 (1,2) - Doesn't flow great due to slider and spacing speed differences.
03:38:293 (1,2) - ^
03:39:328 (2,3,4,5,1,2,3,4,1) - i'm not sure I like how this pattern shifts. Maybe it would be better with more consistency. (Use less angle changes would be my suggestions) I didn't test it though so only do so if it works and is better.
03:43:052 (2) - Random shape and the previous slider isn't pointing towards it. You should fix this.
