Extra:
01:33:543 (1,2,3) - These three should probably be lined up more neatly.
01:59:600 (1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4) - Consider breaking the combos (and spacing) in this stream up more naturally.
02:02:857 (3,4,5,6,7,8,9,10,11,12) - If there has to be a change of pace in the middle of this stream, it should probably be on 9 and not 8.
02:08:343 (3,4,5,6,7,8,9,10,11,12) - Likewise here, consider changing pace on an even beat (uneven combo number) like it's done here: 02:13:828 (3,4,5,6,7,8,9,10,11,12)
02:23:514 (4,5) - This gap is quite large, considering these are 1/4 notes.
02:40:743 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8) - This stream should probably also be more organic.
Otherwise I love this map to death. Get it ranked.
Another:
00:46:571 (1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8) - Consider spacing this so the rhythm is more intuitive.
01:50:000 (1,2,3,4,5,6,7,1,2,3,4,1,2,3,4,5,6,7,8) - Consider having more combos in the slow part here.
Also, the last post is probably right, the sheer speed and complexity of this map probably means having the circles clustered this close together makes it harder and not easier. A more appropriate star rating would be achieved by a little larger spacing throughout. But I suppose, to distance this diff from the extra, it's can be argued that it's fine.
Hyper:
This needs to be comboed up before I can do any reasonable modding.
Normal:
02:24:971 (2,3) - Error here
Easy:
00:52:743 (1,1) - Time between slider and next object is very short
Over all I love it. Please, keep working on it.
