It's playable, and it's not impossible. It doesn't need to be FCable by everyone, since other difficulties can be made. I'd understand if parts of the maps required a hundred taps per second, making it impossible. I'd understand if it's physically impossible to move the cursor fast enough on a section. It does seem out of place at parts, like streams that don't go with the music. But it seems just the difficulty changing at different points you don't agree with. Is that not just like saying "it's too hard for me"? It's not an easy/medium/hard/insane map, so I don't see what's the problem, since these kinds of difficulties are usually less flowing to be more challenging.
