Insane:
00:10:22 (5,6,7) - Space these downward to the right like 00:08:69 (7,8,9) - (except to the right)
00:11:30 (1,2,3,4,5,6,7,8) - Fair.. but kind of unexpected.. maybe centering 00:11:09 (2) - in the middle would make the jump more expecting as the player can see the jump spacing from 2 to 1.
00:17:61 (1) - Hmm suggestion, but don't stack this
~nazi~ 00:39:35 (7) - grid 3 one to the right.
~nazi~ 00:58:91 (10) - ^ but up, not to the right.
02:03:37 (9) - Extend to white tick.
02:06:74 (1,2,3,4,5,6,7,8,9,10,11,12,13,14,1,2,3,4,5) - I really like how this part sounds/is mapped
Hard:
00:38:91 - Note here?
~nazi~ 01:07:61 (5) - down right one on grid 3
~nazi~ 01:08:69 (8) - to the left one on grid 3
~design suggestion~
01:31:52 (1,2,3,4,5,6) - Since it's a hard, I think a jump could be used here. Kind of what you have at 00:42:61 (1,2,3,4) - Here's a kind of idea you can go with, map it how you will.
Overall I think difficulty feels more a bit of a normal, not too much hard. But this is always opinionated, so don't take this to heart.
Normal:
All fine!
