Watch out for the twist section starting from the mid-section, as it's quite long. Especially if you don't have a basic concept of 8-beat stairs, you could definitely struggle. The consolation is that thanks to the slow BPM, you can see the path if you step calmly, and there are resting sections. Looking back now, there seem to be many 8-beat stair songs much faster than this one, so I'm revising my rating.
