It might not hit home because it's a low-level chart, but practically most of the pattern is 16-beat twists. Even from the sight-read section onwards, it's not a 13. This is a crazy song that almost made me fail-clear even when I was clearing 14s and 15s. If there's any reason for its rating to drop, it's just that it's slow enough to bracket, and that's it. However, it's a pattern you need to know how to play to move up to higher levels. Needless to say, it's great for twist practice since it's slow. Don't play it when you're a 13-player; move up and then practice it.

A chart that reminds me of Scorpion King
