Maybe it didn't have as much impact on osu! since the opening intro wasn't there (The whole comic in the beginning). Or maybe it didn't feel that real enough compared to the original. xD [Just throwing things out]
m980 did an awesome remaking this though. I still felt moved by the story when playing the map as I was back in the DS game.
What was the soul you thought it took away, anyway? o3o I'd like to know.
