I'm getting an offset of 69 or so..
Sorry in advance for attacking your new combos
Easy00:58:058 (1) - I would extend this to the next white tick
00:09:093 (7) - This note kinda feels awkward, I think it'll work fine if you just delete it
00:20:047 (1) - Remove new combo
00:24:055 (1) - End this on the previous white tick, notes directly after spinners are tough for Easy
00:40:071 (1) - Remove new combo
00:42:007 (1) - Move this further away from the previous note
00:46:015 (1) - Remove new combo
01:08:077 (1) - This spinner feels like it starts too soon, make it start on the next red tick?
Hard00:53:048 (1,1,1,1,1,1,1) - All the new combos aren't really necessary
Insane00:52:096 (1) - Remove new combo, and group the next 6 notes into two combos of 3
00:55:000 (1,1) - Remove new combos
Not bad! *
