This is pretty awesome in all aspects. Remember, I nazi because I care.
[General/Storyboard]
The Earth sprites could stand to be less pixellated, or at least fixed up so there's not that little bit of white around the edges.
I don't think it's necessary to go back to the Fireflies background at the end.
[Hard]
00:36:968 - I feel like there should be another hitcircle here.
01:22:802 (1,2,3,4) - This is the only 0.5x section in the map, so it feels out of place, and I find it doesn't work that well anyway.
01:38:802 (1,2,3,1,2,3,1,2,3) - Nothing wrong, per se, but I wish this were mapped more to the vocals.
02:14:802 (5,1,2,3,1,2,3,4) - This part doesn't flow like the rest of the map does. The spacing is strange, and some of the "down-hits" (hitcircles and slider starts) land on weak notes in the music.
[Normal]
01:38:802 (1,2,3,1,1,2,3,4) - Ditto the comment on [Hard], but it's less of an issue here.
