Modding:
Extra00:04:661 (9,1) - Increase spacing
00:08:553 (7,8) - Decrease spacing
00:33:688 (1,2) - Fast sliders feel weird, maybe just decrease the spacing between them
00:44:391 (5,6,7) - Weird timing and spacing
00:47:472 (8,1) - Increase spacing
00:51:851 (5,6) - Increase spacing, to show the pause in timing
No hitsounds? No kiai time?
Overall pretty good, still too short, unless you are making more difficulties, make the difficulty at least 5.25 stars.
