Sorry for the very late mod.
Why is the mp3 so quiet?
Taiko:
I am a little worried about 999+ combo, but there is nothing you can do there.
The hitsound volume seems a little loud. You might want to bring it down to 80% like the collab diff.
Collab:
Normal / Nazi mod: (I only did some naziing here and there. I was a lot less strict during some of the messier parts of the map)
00:35:236 (8) and 00:37:391 (9) - I know most ppl complained about this already, but I do not see the pt in having the half speed sliders here
01:07:058 (3) - I would really like it if you kept a consistent pattern between 1,2,3 of this combo (maybe align them ends and starts of each), and I dislike the overlap between 1 and 3
01:44:682 (4) - it would be nice if this did not overlap 1
02:17:832 (5,1) - since this is the only easily noticeable overlap in your section, I advise you move 5 below the line connecting 4 and 6
02:43:357 (1,2,3) - (extremely nazi) move 1 and 2 slightly so the start of 2 does not touch 3
03:41:534 (1,2,3) - if you can avoid stacking these on top of 4, please do so because the overlap onto the 4 looks pretty bad imo
Combo mod:
00:44:683 (1) and 00:45:346 (1) - remove the new combos to be consistent with 00:49:987 (3) and 00:51:313 (7)
03:44:849 (2,3,1) and 03:50:153 (2,3,4) - these slow stacks were quite disorienting for me
Overall nice map. there are some things that I would like cleaned up in the collab, but I guess that is those mappers' style. As a result, I will not complain too much. Star.
