I've been wanting to help you with this for quite awhile, can finally mod this now
~~
General:
Good job, nice song and generally nice map, a lot of thought put into it. But.... I believe Lunar although very instinctive and fun, is quite overmapped, a map like this at 160 bpm doesn't need to be so extreme, and since some people along with you agree as well, I'll try to help you reduce it. One suggestion would be to remove all those triplets and crazy parts, but that would really change the map and need a lot of work, so I'll just point out the more obvious problems.
Crescent:
01:03:682 - Seems like more could be added around these 2 long sliders, keep things simple though.
01:06:682 - Makes this the same as the earlier parts, 4 notes instead of 2 very slow ones, makes it more uniform.
01:25:807 - A note could be added here above the 2 sliders, again for uniformity.
01:57:682 - Instead of 2 notes, link this part together with 1 slider.
Eclipse:
Deserves special general mention, the chorus is heavily overmapped for just a 4.5 star hard diff and low AR, try to reduce the insanity.
00:06:616 - This whole part in the beginning where the pattern goes 'top left, bottom left, top right, bottom right', why not make it go 'top left, bottom right, top right, bottom left'? like an X pattern, would make it play nicer XD.
00:37:057 - This part until the slider is a little sudden and abrupt, not instinctive.
00:38:182 - Make the slider stop here, otherwise the other combo comes too fast.
00:38:744 - Remove this note here, same reason.
01:18:494 - Note immediately after slider with a combo of it's own, not needed and very sudden.
01:27:119 - Sexy pattern, but very overmapped, try to reduce.
01:28:432 - This diamond pattern is really confusing, I don't know whether to move right or left.
01:32:932 - There's too much on screen at once after this slider, especially for such a low AR, you really need to lessen.
01:33:682 - Another quite overmapped and confusing section of jumps
01:40:619 - Don't make these three here along with the next three notes overlap, since your triplets were all very fast before, this can be very confusing.
Lunar:
00:30:684 - This part is too much, one note is enough.
00:39:782 - Too much at this part and the triplets later as well, try to reduce.
00:47:371 - Again too much.
01:18:684 - A little too many of those triplets in rapid succession again, but since this is kiai and chorus you can keep it if you want to.
01:21:121 - The two repeating sliders here don't fit well.
01:35:934 - Quite unnecessary if you ask me, but feel free to just shorten it or leave it like that if you want to.
01:38:934 - Same thing ^, if you decide to keep then keep both of them to make things more instinctive.
01:50:559 - Doesn't seem too smooth here. Just a slider or a note of 2 is enough.
