Looking at the YouTube comments, there's too much downplaying. The section with twist-accompanied drill-style bursts is way too hard to be a 12, and if that affects your stamina for the later sections, it leads to a fail... At least that one section is definitely not a 12. I don't even know how many times I failed because I couldn't read that part.

It was already a very difficult song among existing D10, so it moved up to 12. However, it's still not easy because the patterns are quite tricky for a level 12—for example, you have to step one of the 2-notes while twisting your waist to avoid getting tangled, and you have to step the 16-beat in the second half during a half-twist.
