midnight:
00:01:536 (1,2,3,4,5,6,1,2,3,4,1,2) - Well, these sliders are copy/paste and placed weirdly. You could add some cool shapes here.
00:12:027 (1,2) - 1 can be curved and moved closer to the right side of 2.
00:13:339 (4) - Make this one a single slider and add another note.
00:13:831 (1,2,3) - It does not need to be 100% stacked.
00:18:749 (9,1) - You can move the slider higher.
00:25:306 (2,3,4) - Try making it a triangle.
00:26:126 (6) - You can place it like this:
00:26:617 (8,9,10) - New combo should be here, also move it from previous slider a bit.
00:26:945 (1,2,3) - Space it a little.
00:27:765 (1,2) - You can replace slider with reverse + a note for 2 sliders.
00:34:322 (1) - Too many reverses.
00:36:945 (1) - Same here.
00:39:568 (1) - And here.
00:56:617 (1,2,3) - Curve the sliders.
01:21:044 (7,8) - Circle is too far away from slider, especially that it comes after jumps, and the slider is fast and long.
01:34:814 (10) - New combo.
