Insane:
00:03:567 (7) - This poor spacing is noticeable. This is not nazi'ing; it is obvious and awkward in this case.
00:05:982 (9,10,11) - This is uneven ripple madness. I would just stack them in this case, it's too difficult to get these spaced evenly. The other case of this is done well, though.
00:10:006 (3,1) - This is awkward. Just put the 1 under the 3, it's a lot easier to read.
00:12:622 (1,2) - This does not feel like a jump to me, sorry. It feels a lot more like a stack. :/
00:18:457 (6,1) - This jump comes out of nowhere and feels weird. It's like this was done just for symmetry. The spacing right afterward reverting to normal does not help.
00:21:475 (1) - ...
00:23:085 (1,2,3,4) - Do not feel like sliders. Just make them hit circles, it's a lot easier and funner.
00:37:169 (4,5) - This jump is random.
00:45:620 (1,2) - This section of the song feels slower and softer. Why is there a jump like this there?!?!?
00:48:437 (8,1) - Noticeable spacing issue.
00:51:857 (3,1,2,3,1,2,3,1) - This feels weird.
01:04:332 (3) - Move the 3 please, it'll feel better.
01:16:002 (1,2) - XP
Now, you don't need to fix nearly all of those, don't worry about it. I just feel that fixing a few of those (your choice) would make the map funner and better.
Hard:
Except for the 1/2 stream-ness at parts, it's good! Only thing that I think would make the map better is spacing the hit circles out a bit more. The 1/2 stream feels kind of cramped.
Normal:
Nothing bad
Easy:
Maybe a spinner at the end? I think the hit circles a beat apart shouldn't be that close, but eh.
