ok the major unrankable issues with it
C.Hero
00:03:636 (1,2,3) - extremely incorrect spacing, more distance between 1,2 is needed, look at the timing of the pattern
00:06:600 (2) - note feels out of time, doesnt follow anything within the song at all. this needs either moving to the red tick or deleting
00:09:902 (5,6) - its the same here, mapping to nothing at all is not really allowed
00:17:539 (9,1) - move closer again, extremely bad and inconsistent spacing which becomes confusing to play because the songs patterns are soft at this point making this jump feel totally out of place for your own mapping style within the map
00:22:290 (2,1) - as i said before, completely and totally unrankable. 2 identical sliders right next to each other with a huge speed difference, no tick or visual sign to let the player know, this is completely not allowed
00:27:050 (5) - not a unrankable issue......but really add a new combo here....like wut xD
00:47:370 (1,2,3,1,2,3,4,5,6) - as i stated before this is also completely unrankable, there is no spacing used at all at this point, leaving the player to blindly guess the spacing of each note, the song also does not tell the player unless they already know it extremely well. space this part....at all.....something. not just everything with completely different timing but all the same spacing regardless
00:51:440 (1,2) - again with speed changes what are impossible to notice, without slider ticks these are completely unrankable
02:08:753 (1) - again not visually possible to notice this speed change
02:15:535 (1,2) - again
02:44:018 (1) - again
look for more sudden unexpected speed ups with no visual aid and fix them all
04:55:277 (6,1) - make smaller spacing, totally unexpected and goes against the song at this point
also silenced notes to the point where you cannot hear the hitsound at all are also now unrankable iirc. remove them all
ok well that is Only the objective errors and broken spacing issues within the map that i found. your overuse of 1/4 trip patterns in a song what has 0 of them though tis really not good and breaks the whole flow of the map. fix the unrankable issues first though
