First thing's first. Resnap all of the difficulties. They're not snapped for some reason. Second thing...every difficulty has the same slider velocity. Easy and Lunatic have the same slider velocity. What? In fact, every difficulty has the same difficulty settings. Easy and Lunatic have the same difficulty settings? Easy has maxed out HP Drain?! Are you high?! Also, the difficultys are really similar. Kinda like you just started with Lunatic and took notes away from it without adjusting any difficulty or slider settings... In case I'm not hinting at it enough, FIX IT. Also, make the breaks in Easy/Normal/Hard shorter. 15+ seconds is a little much.
Easy
00:38:77 (3) - Extend by 1/4 beat. (Unless you intended for it to not sync to the vocals or something. >.>)
00:41:77 (3) - ^
01:03:14 (3) - Hmm...maybe this slider should start 1/4 beat earlier, but end on the same spot. That's what it sounds like to me.
01:09:14 (3) - ^
02:14:03 (1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7) - You might wanna break up these combos since they're mostly only on every other beat.
Normal
00:38:77 (3) - Extend by 1/4 beat.
00:41:77 (3) - ^
00:50:77 (3) - ^
00:53:77 (3) - ^
01:03:14 (4) - Hmm...maybe this slider should start 1/4 beat earlier, but end on the same spot.
01:09:14 (4) - ^
02:51:06 (2) - Move 1/4 to the right. At least I think it sounds better.
02:53:97 (2) - ^
Hard
00:03:15 (3) - Hmm...maybe this slider should start 1/4 beat earlier, but end on the same spot.
00:09:15 (3) - ^
00:14:22 (2) - Move 1/4 to the right.
00:38:77 (3) - Extend by 1/4 beat.
00:41:77 (3) - ^
00:50:77 (3) - ^
00:53:77 (3) - ^
01:16:64 (9) - I don't think this is trying to sync to the vocals, so I don't think it's a problem.
01:26:77 (3,4) - No.
02:50:97 (2) - Move 1/4 to the right.
02:53:97 (2) - ^
Lunatic
00:14:22 (2) - Move 1/4 to the right.
00:38:78 (3) - Extend by 1/4 beat.
00:41:78 (3) - ^
00:50:78 (3) - ^
00:53:78 (3) - ^
02:31:65 (1,2) - Yeah, maybe spread these apart. It'd be fine if it was more predictable.
