[General]
Tick rate 2 fits this song best
[Easy]
Your new combo use seems to be random at best. Try to aim for a new combo every 2-4 tall white ticks so keep them grouped to fit the music.
So for example, you would have a new combo at 00:20:841 (4) - and remove the one at 00:22:253 (1) - , a new one at 00:23:665 (3) - and remove at 00:24:371 (1) - and so on.
02:29:312 (2) - This would play better like this
02:40:606 (2,1,1) - These would benefit from a similar change:
[Normal]
OD +1 or 2
00:05:666 (4,1) - Spacing is way too close for a Normal.
00:53:312 (3) - 4-hit short repeat sliders are bad for easier level difficulties. I'd try something different here.
00:55:076 (2,3) - Try to avoid stacking on the ends of sliders with 1/2 rhythms in Normals. Especially easier ones like this.
00:56:135 (4) - Same as earlier. Applies to other instances later as well.
...well, I started it, anyway. I'll try and finish it up later when I'm not dead tired.
Edit:
If anyone wants to pick up where I left off, feel free. I don't think I'm going to have time to take care of this in the near future.
