You may want to check the spacing of the blue 2-6 at ~1:21 - they're all a half beat apart but the spacing is a bit weird, unless it's matching the video?
If it's to do with matching the video, then I have no problems with it. If it isn't, then please fix
Only the 4-6 are spaced like that, I think. That is meant to follow the video, but not so closely that it has to be that way, I guess. I've changed it now.
Spinners are generally a good idea for score variability but it doesn't have to be there if the song's got no room for it. One at the end almost fits with the elephant though.
I'm experiencing similar video problems, but that's not what I'm here for; I'll figure that one out soon enough.
While trying to recode the video to play better, I noticed the VBR audio track... So I watched the video with that audio, and I think the audio track from the video would be better to use, with all the sound effects and etc.
No, I will most likely not add another difficulty. I wish I could get around to Osu again, I left like 5 beatmaps unfinished, but I was always terrible with the timing stuff... Hell, Tentai Kansoku even suffered from it in its final form, because I made the mistake of making the song I wanted to do the most as my first beatmap. Because it's AWESOME.
I did this as a single difficulty due to the video syncing stuff. It would be difficult to really work that around something harder, although I'm sure it's doable. Maybe someday...
