00:02:349 (4) - could move to 00:02:191 - to show a pair with 00:02:665 (1,2) - / 00:05:665 (3,4) - same thing
00:30:612 (2,3) - this feels kinda underwhelming for the build-up + doesn't really follow anything. i think you could do two repeat sliders or a stream, delete 00:31:086 (1) - and add a circle on 00:31:401 - instead
00:31:244 (3) - 放2的上面加大00:31:244 (3,1) - 之間的距離比較好, 畢竟00:31:401 (1) - 的聲音比00:31:244 (3) - 要強
00:52:559 (1,2) - Could increase sv and do this rhythm pattern where the bass actually hits: 
00:58:716 (1,2,1,2,1,2) - imo these bass feels really strong and worth making more of them active. Could consider doing a similar rhythm pattern with 00:55:243 (1,2,3,1,1,2,1,2) - .
01:23:068 (3,1) - 沒必要放這麼遠, 01:22:752 (2,3) - 可以試試搬到下面把01:23:068 (3) - 的滑條尾疊在01:23:700 (2) - 的頭上
01:37:085 (1) - possibly offscreen, could move the slider up like this: https://i.imgur.com/7HNFnta.png
01:48:453 (1) - i'd personally start this slider on 01:48:611 - and add a 1/4 slider on 01:48:453 - instead to follow the synths. since you also seem to be following it at 01:49:558 (1) -
02:00:533 - Quite worth mapping so there is a sudden pause in movement connecting 02:00:296 (2) - which would better fit the music.
