-First off, you don't need Tamayurahotaru ABSOLUTE CASTAWAY as tags, as those are already the title of the map.
-Second, the timing is wrong, these are what i think are more correct, but you can probably find an even more accurate:
All points need the 3/4 waltz timing to fit best. And also to set offset, just look at the time and type it on the offset bar, example: 00:50:409 = 50409 offset; 1:00:860 = 60860 (the first 60 means one minute passed, thats why 1 minute = 60 000 offset, easy math
Also all these timing points mean you need to fix the whole inherited points (green lines), fix slider lengths, etc, so now i did a new diff for me to just show the other stuff of the map with the timing you had
00:09:964 (3) - Don't place this circle behind the slider, (overlapping this is called) makes it hard to read.
00:39:964 (1,1,1) - I think you should remove all these New Combos, having these 4 circles 00:39:535 (1,1,1,1) - be the same combo is better looking and less confusing.
00:43:178 (1,1,1) - Remove, same as above ^
00:45:428 (1,1,1) - ^
00:46:821 (1,1) - Make this slider longer, just like in 00:41:357 (1) - , because it is confusing, the first slider was slower and the player was used to move less than now, so making the slider have different speed but being same size makes it hard to read.
00:48:107 (1,1) - Remove combo again
00:50:357 (2) - Please add New combo here, different slider speed = different combo
00:51:214 (1,1) - Remove combo
00:53:464 (2) - New combo
00:53:892 (1) - Remove combo
01:06:857 (1,2) - Switch combo between these 2 notes (meaning remove combo on circle 1 and add combo on slider 2)
01:09:857 (3,1) - Switch combo here too
01:12:000 (3,1) - Switch combo
01:22:500 (1,2) - Switch combo
01:23:142 (1) - Remove Combo
01:23:571 (2) - NC (means New combo)
01:29:410 (1,2,3,4,5,6,1,2,3,1) - This is the wrong rhythm, not following song correctly, you should do like this:
Also give all these circles the same spacing between each double: example: circle 1 to 2 have 0,5 spacing between, circle 3 to 4 have 0,5 spacing between, etc
01:33:857 (4) - NC
01:40:071 (1,2,3) - Very confusing and hard to read, please just turn the slider end, of slider 01:40:285 (3) - to the right, so it goes out instead of in the pattern (means no overlap)
02:10:285 (2) - NC
02:11:678 (2,3,4) - Please delete these circles, there is nothing in the music to be represented as a stream, and also the jump to next slider is too hard to do, specially when reading is hard
02:12:428 (2) - NC
02:12:857 (3) - NC
02:13:607 (1) - Remove NC

02:25:285 (1) - Remove NC
02:25:714 (7) - NC
02:27:000 (4) - NC
02:32:357 (1) - Remve NC
02:32:785 (1) - Remove NC
02:32:785 (5,6) - Make these 2 more distant, too close means click too early, which is combo miss.

03:44:142 (4) - NC
03:45:000 (1) - Remove NC
03:45:000 (1,1) - Don't overlap this slider, hard to see and since slider speed change, it causes combo break too, i suggest placing it somewhere else
03:46:928 (4) - NC
03:47:357 (1) - Remove NC
03:50:678 (1,2,3,1,2,3,1,2,3,4) - Not good to place a stream here, doesn't fit the song well, i suggest deleting all blue ticks and give pattern more spacing

03:59:357 (4,1) - Switch Nc for better reading

04:12:428 (1) - Here you need to remove NC
04:13:607 (1,2,3) - Actually, triple doesn't start here, it starts 04:13:500 - here so move circles to this point
04:14:785 (1,2,3) - same here, move to red tick behind it.
04:15:428 (4) - NC
04:22:714 (6) - NC
04:23:142 (1) - Remove NC
04:22:714 (1) - This slider is also very distant, but if you really wanna keep it, at least point the end of slider to the next circle, for better movement.

05:29:571 (6) - NC
05:29:785 - This part should be a stream, it has many beats for it, and also it is very confusing spacing, so close, so please do something like this:
05:36:000 (3,4) - Give these sliders new combo color for each
05:43:928 (1,1) - Remove NC
