very twisty, song just never wants to end, also beware of the cheeky bursts

There is a gimmick in the middle, but you can pass that easily; just survive the twist run at the very end to clear.

ending is way too twisty and harrowing to be lower-end of the 21s, even if the bpm is low

The early section isn't very difficult, but after the clock-face section crossover (be careful not to miss the timing for the holds), the movement range gradually widens, and it's composed of high-stamina twists. Although the BPM is slow at 133, it mixes in up to 8-tick, making it a chart that definitely earns its 21 rating.

The twists aren't exactly easy. However, compared to other twist songs of the same level with higher BPM (like Euphorianic, Love Dance Zone, etc.), it's much easier. Except for the high-angle final kill, there's nothing that poses a significant threat to a 21 player, so based on full accuracy, it's around mid-low 21.
