wow i promised to mod this orz
Well I played it a few times, flow feels alright, mapped pretty good. I'll just point random things/suggestions I guess.
00:15:416 (5) - can make this a 3/4 slider, optionally you can lower the volume for the sliderend as well.
00:25:158 (4) - feel like these should be circles, 00:25:313 - could use a bit more emphasis, but it plays well as it is so dw, its just a suggestion.
01:01:499 (5) - i know it looks pretty as it is but i think this could have a bit more emphasis, but honestly i don't like the whole pattern, maybe you can tilt it as it spins around so its easier to read. Possible solutions:
make 01:01:499 (5) - a 1/2 slider
OR
01:01:499 (5) - make a jump
01:04:901 (3) - x:101, y:130
01:09:231 (5) - could be a 1/2 slider, this opportunity repeats throughout the whole map so dw, as long as it's consistent its alright
01:20:674 - - 01:23:148 - can we insert a break here, that drain will kill HR players who f'd the jumps here 01:20:055 (1,2,3,4,1) -
01:40:468 (1) - make the actual slider a whistle instead of the slider start? and this needs a strong hitsound too 01:40:468 (1) - maybe a drum clap
01:59:643 - - 02:00:571 - could make this a stream (sounds weird in the song itself but to me it definitely sounds like the drums are spamming at 1/4 or faster)
02:08:148 - 02:08:225 - 02:08:303 - could be a triplet
02:08:921 (1,2,3,4,5,1,2,3,4,1,2,3,4,1,2,3,4,5,1,2,3,4,1,2,3,4,1,2,3,4,1) - thank god slider ticks exist

02:26:859 (6) - circle, start stream here 02:27:014 -
02:35:364 (2) - definitely a combo breaker, pls no, way too far from the 1/4 slider stream, the emphasis is alright, but in terms of gameplay, maybe i'm just noob, idk

02:48:973 - parts like these are screaming for a stream, just my opinion
03:06:602 (4) - x:386, y:123
03:07:529 (3,6,2,4) - i think these babies want more emphasis, why you bully them, increase spacing for them?

03:25:313 (5,2) - this stack looks off o.O
03:44:797 (4) - nazi: x:67, y:250
03:59:952 (6) - ^ x:205, y:170
04:28:483 - i think you can fill it in with a circle man, 04:28:406 - sounds like a start of a stream, i know those drums are hard to hear but it's kind of noticable, maybe just me idk
04:43:560 (1) - moth, the center red anchor point: x:256, y:156, it will fix the start/end symmetry issue (at least to my eyes). Checked it with photoshop, it's 100% perfectly symmetrical, well done

Great map, good luck approving it <3
