Confirming the silence hitsound thing, playability issues, slider speed issues, general design issues mentioned by others. This is just a quick glance to confirm what has already been mentioned (not as detailed as it should):
01:56:435 (1) - this is unrankable. Sliders are not supposed to speed down and speed up in themselves.
04:17:675 (1) - unrankable. This is totally offtimed (too early)
04:18:942 (1) - silent note, silent sliderside, silent everything. Also using bpm changes to manipulate slider speed is invalid.
04:52:280 (1) - see other slider
06:07:511 (1) - ^
Stuff I consider overmapped:
01:00:935 (8,9) - why is there a triplet?
01:16:627 (9,10) - ^
01:31:397 (4) - I dont get this repeat slider
02:05:435 (8,9) - this jump is unjustified and totally sudden
02:07:051 (6,9,10) - wow, what is that for a hitobject timing. how unintuitive
02:55:166 (7,8,9,1) - I wonder if this jump is just placed for the intention to make it even more difficult
03:02:781 (1,2) - whats with this triplets everywhere. why are they existant?
03:06:474 (1,2) - this follows nothing, not even anything you attempt to "remix upon the song".
03:38:897 (4,5,6,7) - ^ (the guitars do something else, the 2nd slider is redundant, since the tone you follow still should belong to the first one)
04:58:165 (4,5) - *gasp*
Other stuff that I noticed while taking a glance on it:
00:39:590 (4) - why is that a slider and not two circles?
00:39:590 (4,1,2,3) - this sounds off, the sliderends make this entire attempt to make the player alternate to the choral sound like poop. Making the first two sliders end on red ticks works waaaay better (soundwise)
01:37:051 (1,2) - what an ass move
01:41:897 (2,3,4) - ^
01:48:935 (1,2) - inconsistent with previous mapping
03:37:974 (1,2) - just another ass move to make people break
03:49:197 - suddenly, slow piano, suddenly, boring 1/2 sliders. There are so many syncopes you could make a use of, yet you simply copypasted 1/2 sliders everywhere. Pretty disappointing. Also this part lacks circles.
tl;dr: the entire map is filled with borderline playable, forced-difficulty, cluttery and unrankable stuff and is an attempt to be "creative" by ignoring the song and what is suggests. That's my opinion. My personal. Yet I confirm the flaws the other BATs mentioned here so far. Please fix them.
