I'm new and modding, and can't find that much problems, but hell
Normal
01:00:93 (1,1,1) - looks colorful, but is it needed?
01:02:06 (1) - rebound once more?
01:07:31 (2,3,4) - colorful, is it needed?
01:12:37 (1) - might be too hard for normal, but make it start on the next red tick, end the same place
01:23:24 (1) - remove new combo?
01:29:24 (1) - ^
01:35:23 (2,3,4,5) - nudge this up 1 level 3 grid up plz, looks neater
Hard
01:00:93 (2) - remove new combo?
02:06:54 (9) - I don't know, keep it, move it to the next white tick or the white tick before(not sure, white tick sounds better to me)
02:17:97 (8) - Remove this, it's useless
02:58:83 (3,4) - move 1 level 3 grid down
Overall, great map, except normal just doesn't sound right to end it were you ended it.
what I modded is my opinion, so feel free to decline, not that many problems either
Also, I got bpm of 80, so 160 is just fine
Hope this gets ranked now, priority plus 1 plz
