Greeting. Great map but there are some things I'm concered about.
*Isn't HP drain too big? I thinkg something about -1 from currect would fit better as map has a lot of various 1/4 rhythm.
*00:10:464 - having unclickable object here doesn't give a proper feedback to a player as a new music stanza is introducing and you start it with passive gameplay element such as sliderend. You can, for instance, the same as for 00:01:964 (4) - .
NOTE: 02:08:130 (1,2) - / 02:09:463 (1,2) - etc. — the same.
*00:10:798 (1,2,1,2,1,2,1,2,1) - NC for 00:11:798 (1) - doesn't seem reasanoble to me. If we listen to 00:10:798 (1,2,1,2) - pattern has clearly audible transition right here 00:11:464 - and you emphasis it with NCing but on the other hand 00:11:798 - doesn't have such transition. Remove NC for better feedback and music reflection seem pretty logical to me.
The same as above 00:12:631 (4) - / 00:15:298 (4) - / 00:17:964 (4) - etc. — new music stanza so having these without NC looks pretty senseless and doesn't really refflect the track.
*00:16:131 (1,2,3) - meaningless and inconsistent 1/2 gaps. Is not really a good idea to have such kind of things is Extras. Just two 1/2 sliders is pretty good solution for this kind of things.
*Also, you are silencing both slidertick.wav and sliderslide.wav which is unrankable. For instance, 00:01:964 (4) - / 00:04:631 (4) - / 00:07:298 (4) - etc. — this piano fadeout covers sliderticks and they become unaudible and don't give proper feedback.
*00:26:797 (1) - / 00:28:797 (1) - / 00:30:797 (1) - etc. — intentioanlly ignored 1/2 prominent sound isn't a good way to give feedback. This is a rhythm "slowdown", I can't see any proper reason to make that. 1/2 reverse works pretty fine here.
*Spacing from this part 00:38:797 - doesn't make much sense to me. 00:39:631 (4,1) - / 00:42:464 (3,1) - / 00:43:464 (3,1) - etc. — too way inconsistent and random. The same goes for 00:40:131 (2,3) - / 00:42:131 (2,3) - / 00:43:131 (2,3) - etc. I'd recommend you to make it more consistent.
*00:57:797 (3) - / 01:01:464 (5) - etc. — lack of rhythm emphasis. If you mapped this according to the stongest piano sound then unclickable sliderend should've been clickable. Others intrumentals isn't emphasized either. I suppose two 1/2 sliders is a good idea. Or maybe 3/4 and a slider? A solution as well.
*01:02:131 (1,2,1,2) - the first part is more prominent than the second but spacing is made vice versa. 01:02:464 (1,2) - these have quite strong sound 01:02:464 - here and 01:02:631 - here. Less spacing for 01:02:131 (1,2) - and more spacing for 01:02:464 (1,2) - would bring more emphasis to this pattern so far.
*01:06:464 (5,6) - just compare to 01:05:797 (1,2) - . Pattern is the same but 01:06:464 (5,6) - this patterns has prominent 1/4 sounds under these sliders.
*01:07:047 (2,3,4,5,6) - the same as above but contrary. Pretty inconsistent stream.
*01:13:631 (1,1) - spacing here seems like 1/1 spacing just before this pattern, may be hard to read.
*01:16:131 (2,1) - compare to 01:17:631 (1,1) - . Pretty similar patterns and music but spacing is too way different. It's better to keep consistency for such kind of patterns. Stream wouldn't hurt instead of 01:06:464 (5,6) - .
Some rhythm inconsisties and concering moments for me:
*01:27:797 (8) - sorta weird repeat with pretty audible sound 01:27:964 - . / 01:33:464 (1) - I cannot understand which instrumentals were you according while mapping this. It has this audible sound right here 01:33:631 - . / 02:34:297 (1) - and 02:44:963 (1) - having an ignored downbeat isn't quite consistent withing this part of the song. / 03:36:797 (4) - and 03:39:464 (4) - the most prominent sound goes for the repeat which has to be clickable. / 05:01:377 - the same. Lack of rhythm emphasis as for me. Such strong sound and not clickable. / 05:12:377 (2) - if we compare this to 05:18:376 (2) - we can hear that the second slider has prominent sound starting from the red tick but on the other hand the first slider has the prominent sound on the blue tick. The same goes for 05:18:376 (2) - blue has sound on it. A solution could be making these spacing issues consistent which aren't and make these sounds clickable which aren't as well.
Some spacings:
*01:54:797 (1,2,3,4) - kinda lacks spacing emphasis 01:54:630 (2,1) - . Try ctrl+j out. / There are also a lot of inconsisties 03:47:130 (2,1,2) - and 03:49:797 (2,1,2) - the same pattern for the same music but it has a huge difference between. / the same goes for 03:59:130 (1,2) - and 04:09:797 (2,3) - .
*04:43:377 (2,3,4) - you definitely forgot to change sampleset to soft.
just my thoughts, nothing extraordinary
