the storyboard has to be removed. it's literally mentioned that it only works on the ImpossibleDystopia.osu difficulty and yeah, no. that's not gonna work. remove it. there are 3 diffs, and that's gonna definitely intertwine with the rest.
One suggestion; it is pretty difficult, but it is labeled impossible so I'm not surprised. If its a single difficulty beatmap its fine, but if you want it to be accessible to more people, then more difficulties to choose from would be nice :) other then that, it was fun :D
