to kind of elaborate on what monstrata said about 1/4 sliders giving a rushed feeling:
in terms of how 1/4 sliders play, it does require some amount of holding which 1/2 circles very much do not require. this holding gives tails of the sliders some sense of value and within this map, you use both rhythmic representations of the 1/4 sliders and the 1/2 circles to represent roughly the same sounds in the music. the changes you have between these circles and sliders are curious, because from looking at this maps its as if you felt they have the same value. because this seems to be your approach its almost as if there is really no definition you have created, and thus a lot of people find this map inconsistent, and in terms of using object mechanics correctly, low quality.
