[General]
there should be spaces in the source, so "NARUTO -ナルト- 疾風伝"
[Easy]
CS feels unecessarily big (also causing some sliders to touch the playfield border), I would just go with CS3
00:20:886 (4,1) - spacing
00:24:675 (2) - clap end
00:45:233 (3) - the blanket here can look better
[Normal]
AR could use a slight bump to make the stacks for readable, try 5.5
00:21:044 - try adding a circle here
00:53:575 (5) - swap for a 1/2 repeat slider to cover the drum roll at 00:53:735
01:14:110 (5) - ^
[Hard]
00:20:728 (4) - the number of repeats here is a little arbitrary, would be best if you have a triplet here and start the repeat slider at 00:20:886
01:24:858 (3) - NC
this diff follows DS very strictly, but I think you can break free of it in some occasions for better emphasis e.g. gradually increasing spacing for 00:41:864 (2,3,4,5,1). Just some suggestions for future mapping choices.
[Insane]
00:11:412 (3) - missing clap
00:24:991 (1,2) - flows better if you arrange it like this:
00:48:441 (4) - making this two circles would play better, since there will be a clickable object for the clap at 00:48:602
[Kage]
tbh i would name this "Houkage", since the song name "Guren" has the meaning of redness in it (hence red houkage lol)
00:20:570 (3,4) - this angle plays a bit weird, i would lower 00:20:570 (3) a bit more
00:30:360 (2,3,4,5,6) - this jump feels too overpowered for this section, you should tone down the spacing a bit so the jumps in the kiai stand out more
00:57:907 (8) - NC here instead of 00:58:067 (1) to follow vocals better
01:06:088 (3,4,5) - this flows a bit awkward, a more natural movement would be to put 01:06:249 (4) at x:44 y:180
01:22:933 (2,3,4,5) - not a big fan of how this pattern plays, maybe move 01:23:094 (3) to somewhere like x:284 y:208
ok call me back after
