[General]
offset: +7 (450)
The time between the 2 kiai is a bit long (if it's a re-kiai technique), make it just 1/2 or 1/4 is enough.
[Easy]
The diffculty setting is a little harsh for such a Easy imo. HP,AR,OD all -1.
00:12:616 (1,2,3) - imo in this 0.75x part, you don't need to still follow the Distance Spacing multiplier very strictly, just make 1/1 circles have same spacing like 00:29:138 (2,3,4), means don't have a part stack with each other.
00:16:095 (2,3,4) - ^
01:15:008 (1) - whistle? (both beginning and end)
[Normal]
00:27:399 (6) - i suggest use a 1/2 repeated slider here. as it's very near the next section and about to start.
00:50:877 (3) - looks a little strange (because of 4's place), try this?
01:13:486 (1,1) - whistle?
01:40:660 (1) - add repeat?
[Hard]
00:08:269 (5,6,7) - why the spacing is larger here... it's not a big deal but feels strange to me.
00:15:877 (6,7) - spacing is a bit far, compared to 00:15:008 (3,4)
00:25:877 (7,8) - would be a little hard..?
00:31:747 (1) - notes comes just 1/2 after a spinner is not so good, maybe end this 1/1 earlier and then add a note at 00:34:790?
00:45:225 (1) - clap miss
01:41:095 - add a note?
[Insane]
Personally i think this song fits 1/4*2 (notes like oo oo) a lot, consider to use some?
00:17:508 (4) - i feel this is a bit extra...remove?
00:40:008 (4,5,6,7,1,2,3,4) - not complaining but this part is not that fun imo...
01:05:551 - add a note?
01:15:660 (2) - maybe add whistle too.
