I love this song, and I love this beatmap. This is one of my favorite beatmaps ever.
Kharl, you gave me the original offset I was using, too. I never know what to believe from you.I'm sorry about that. Well, just think of it as a fine-tuning. It is hard to notice a 20-30 ms error in offset listening to metronomes alone. You'll catch it either when you autoplaying your map in the editor or when you test-playing it. So don't hesitate to adjust your timing if something seems wrong, even if you have completed your map (which is something I usually ended up doing when I've done placing the beats, and found out that my initial timing is off by 10-30 ms almost all the time ^^" ).
