It wouldn't be surprising that the BPM of the song used in this level is 128, which contains lots of quaver notes, and all notes are reserved. It is hard for average players to get all the notes in 256 BPM. What's more, the road is so narrow that you would easily get off track. There are neither death collision boxes nor checkpoints, you can only restart if you miss. Besides, the camera is either too close or too far from the line in most sections. At a place you must triple hit, the camera changes suddenly, which causes the player to panic.
