* = most definitely optional
Easy:
-Just remember to compensate for early timing when using Inherit sections (after the first break, especially).
Other than that, no complaints, really.
mrtn's Normal:
-Same thing I mentioned in Easy (without noting specific sections, since a simple look at the map will show you where you need to fix it).
-00:02:75 (1) - Add a Whistle, it adds a nice touch to it.
*-00:02:75 (1) - Remove the New Combo mark.
-00:45:70 (1,2) - Soft hitsound volume feels so out of place here.
-00:46:84 (1) - Remove the New Combo Mark.
-01:15:02 (2) - Add a New Combo mark.
-01:33:66 (3) - This Clap is out of place. Remove it. Possibly replace it with a Whistle.
-01:35:93 (6) - New Combo mark goes here.
-01:51:84 (2) - Remove the Clap.
Hard:
-Same thing I mentioned before with inherit sections.
-00:02:75 (1) - Add a Whistle.
*-00:02:75 (1) - Remove the New Combo mark.
-00:46:61 - Soft section is so out of place. Don't do that. ):
*-01:16:27 (1) - What is this mapped to? Just curious. I mean, I know that there are plenty of other overmapped sections in this, but that grace note just seems weird.
-01:57:30 (1,2,3,4,5) - Musically-speaking, this is an awkward set of notes to come back in on. I'd suggest removing this then reinputting the break for the sake of feeling much less awkward.
-01:58:20 (6) - New Combo mark goes here.
-01:58:66 (1) - Remove the New Combo mark.
*-01:59:57 (3) - This feels like it should be 1/4 earlier, then respaced. But then again, the other parts are consistent with it, but the rhythm feels more correct on the sliders.
-02:03:43 (6) - New Combo mark goes here.
*-02:04:11 (1) - Remove the New Combo mark. It works either way, really. Go with whichever you prefer.
-I honestly feel like you should map until 03:15:482, since that feels like a more natural place to stop (since where I just mentioned is the end of the chorus). Where you have it end leaves the player hanging, wanting more (at least that's how it felt to me), at least to go through the chorus one last time.
Starred.
