00:01:688 - As much as I like the gimmick in this one, I don't think players are able to distinguish the note and the spinner quickly in this difficulty. Furthermore, this will cause miss for lots of players because the note and the spinner has too little gap in between them. I suggest having a 1/8 gap so players can easily distinguish them.
00:01:688 - Can you also do SV x1.5 for the ninja Finisher in the beginning. This greatly affects the other spinners throughout the map to have the fade-in effect when the very beginning SV is set to a very high value, which is quite unintuitive and too challenging for this difficulty.
