Can't really make a new topic about a beatmap that already has one meant for it, so apologies if this is considered necroposting.
I really don't think the map is that good; at least not the hard difficulty. The circles and sliders are all over the place and make it feel more like a puzzle (a tedious one and confusing one) than a beatmap. Right at the start, it already gets confusing with the circle positions. It kind of seems like the creator of the hard difficulty just put circles down in random locations. They're very cluttery and hard to track.
Haven't tried out the other two, which I hope don't suffer from the same problem.
