Hello Spaghetti.
I'd like to mention a few of things in the hardest diff.
00:07:597 (1,2) - I don't think this is good, it makes it look like (2) is a 1/2 slider rather than a 1/4 slider
anyways that aside
I really honestly think the kiai time has really inconsistant spacing values, lets look at them. (woo)
00:29:746 (1,2) - why are these spaced literally across the screen from eachtother? Yes I understand you were emphasizing the vocals, but still, there's NO NEED for you too space them this terribly far, also it's inconsistent with 00:31:849 (5,1) - this, it's the same thing but 00:31:849 (5,1) - here it's spaced a lot less then 00:29:746 (1,2) - here.
00:34:232 (1,2) - again, why is this spaced so far? It's closer together than 00:29:746 (1,2) - this but it's still further than 00:31:849 (5,1) - this? Again inconsistent spacing.
00:38:438 (5,6,3,4) - (3) and (4) have an very noticeable difference in spacing, yet they should be the same.
Okay, thats all the spacing things, but there are still some questionable moves in the hitsound department :/
00:34:373 (2) - why is there no finish here if there is 00:31:989 (1) - here? They both obviously have the same kind of "power" in the song so they should both have finishes!
