Halcyon

The runs are long and the layout drains a lot of leg strength. The stairs and side-twists that pop up in between are also hard to position for, so your gauge is easy to lose.

hard to clear and scoring, too much stairs that can kill you fast. And remember the last hold.

Get to 25 with V 3 as soon as possible.

The run in the middle is long, but there are quite a few empty sections overall... Personally, I don't think it's high, but it's not quite mid either, so mid-high.

It's brutally exhausting in terms of stamina. If you recklessly ignore stamina management just because the frequent half-note runs seem short, there's a high chance your stamina will be gone before you even reach the second half. If you're strong in stamina, it might reach mid-high... but I'm not sure.
