Try this offset: 598
It might just be me, but the audio's fairly quiet... and even though you more than halved the hitnotes, they're still kinda loud...
Easy-
00:00:57 (1) - The timing panel here is messy, sometimes messes up the first slider
00:54:57 (1) - hitsound please~
01:01:90 (4) - ^ (on the end only)
01:15:07 (3) - only nazi-able point I saw during play, line up better please
I suggest you remove all kiai for easy, the effect is very very weak...
Normal- this is pretty hard
00:05:93 (1,1,2) - fill in some hitsounds please
00:20:93 (1,2,3) - kiai+finish effect? in that case, not bad
00:45:93 (1,2,3,4,5) - maybe fill in hitsound gap
00:57:93 (1,2) - I just don't like this part... doesn't sound well after those fast sliders and claps
01:13:93 (1,2,3,4,5,6) - not whistles on ALL of it..
weeee fast+short sliders = fun~
Hard- kinda insane
waaaaaah all the beats are messed up near the end, nothing is snapped properly... ohhh I see why... BPM 180.6?
00:05:90 (1) - same as normal
00:31:22 (7,1,2,3,4,5) - have something indicate the claps ended... or add more, cuz the claps seem to stop randomly
00:45:88 (1,2,3,4,5,6,7,8,9,10) - make the whistle combination sound like the clap combination in the combo prior to this one
01:07:54 (3,5) - no like rapid claps like this, messes your hitsound flow
01:10:21 (3,6,7,8) - ^
01:12:88 (2,4) - ^ and so on..
01:13:88 (1,2,3,4,5,6,7,8,9,10,11) - after all those hitsounds, this part doesn't sound appealing without 'em
01:35:20 (1) - eww whats with the clap
I know what effect your trying to with the spinner spam at end, but it doesn't work well since the spinnerspin sound doesn't seem to get quieter... Did you just get lazy? >_>
Remember to resnap all notes after changing offset, and redo breaks, too
Hitsounds generally creative and not bad~~! And I'm so glad you didn't use those Phoenix Wright hitsounds in those old maps xD
