01:40:235 (1,2,3,4,5,6) - the distance snaps which are between each circles(2, 4, 6) look smaller than similar patterns (likely 00:21:059 (1,2,3,4,5,6) - and 01:00:647 (1,2,3,4,5,6) - ) even all of these patterns have same sounds.
How about expanding the distance snap a little bit? such as 1.6 according to the other same patterns.
01:49:826 (4,5) - any reason spacing gets large here? should keep it consistent with your other 1/2 spacings; ie 01:46:424 (2,3), 01:48:589 (6,1), etc
02:00:338 (1) - I see the slider velocity is same with Moonblast. However the slider velocity is too slow to keep the cursor and to press the keyboard button for players who can't play more than hard level difficulty.
How about increasing the slider velocity? I'd suggest 0.5 would be nice.
