So I'm finally here.
[General] - Most importantly, the map doesn't seem to download with the [Normal] difficulty. Try Full Submitting and see if that fixes it.
- You could consider mapping an [Easy] as the song isn't that long and it completes the difficulty spread.
[Insane]00:17:645 (1,2,3) - Stacking makes this pattern look a little strange while
playing, if you care go ahead and change it.
01:05:423 (6) - Most sliderend stacking beatmap occurs 1/4 after the slider ends, this one occurs 1/2 after the slider ends. Seeing how it's a bit confusing, consider moving it like
this.
01:18:979 (2,3) - Hm, the stacking makes things pretty odd here, too. Try a different pattern with less overlapping?
01:33:867 (3) - Different note but same idea as above.
[Boss Taiko Oni] - I'd advise using this taiko background for several reasons... it saves filesize by converting to .jpg format, the picture is no longer stretched out and it avoids the font "Comic Sans MS" which a lot of people don't like.
[Hard] - For a [Hard], I probably would have expected a few less 1/4 patterns, but it works for now. Probably would have fit the spread better without them, though.
[Normal] - I probably would have used a slightly higher slider velocity to avoid a lot of overlapping, but I suppose what you've got works.
01:00:979 (1) - For the easiest difficulty, this note comes far too soon after a spinner and new players can have a hard time adjusting. Mapping through the spinner could work.
That's all, really. I'm tired right now, so expect a few more things later. Just PM me after fixes and thanks.
