The front is easy, but the twist in the second half is difficult.

The late spike is hopeless, but it's not long enough to be a problem, and the early part is too easy.

I cleared it pretty smoothly for a mid-level chart. The final crossover is tough, but there aren't any major hurdles before that, and the potion is decent, so based on break on, I think it's around mid-low. Just be careful with the final part, as it's easy to fail suddenly.

Based on full HP, you can survive even if you throw away the last 5 seconds, but it's very disorienting on a sightread.

You might find it a bit confusing to hit the very end with straight notes, so be careful. Other than that, just watch out for a few side twists, and the hold portions are well-placed.
