04:43:169 (1) - 04:43:874 (1) - the changes in volume seem a bit abrupt here, it was noticeable during gameplay, maybe make the changes more gradual
03:14:801 (1,2) - these should be closer together to indicate it's a 1/4 gap, similar to this 03:16:125 (5,1) -
03:08:404 (1,1,1,1,1) - this could be made much more intuitive to play and read. at this difficulty level, the NC's won't be enough for players to recognize what rhythm the map is changing to fast enough, especially with the added uncomfortable movement
02:58:477 (6,1) - I think the spacing should be larger here for emphasis on the second slider
02:58:257 (5) - maybe Ctrl-G this to make the movement more intuitive, especially at this difficulty level
02:50:536 (8) - up until this point you've been using circles to represent this part, changing to a slider here doesn't make sense
02:48:992 (4,5) - imo the spacing between these should be consistent with the same previous pattern 02:48:330 (2,3) -
00:19:875 (1) - 00:33:992 (1) - I think you should use the same object to represent these considering it's the exact same rhythm, either a circle or slider for both
I agree, I think it's odd to represent it with 1/8 and then switch to 1/4. imo using 1/4 is fine here because of the difficulty level but not both
