BRAIN POWER

Even if you memorize the gimmicks, it's not easy to mash, and the red-blue and blue-red brackets that pop up in the middle of the drills are annoying. Draining stamina with the jack is a bonus.

the gimmicks are gonna quickly drop your accuracy, not to mention the jacks and the ending brackets. overall just hit the notes and pray like the person below me said if you are looking for a pass

this lowk hard, mash and pray

You can use brackets for the first part when the gimmick starts, but the final part must be hit with a clean single note.

If you ignore the red notes that appear at 1:57 in the NevSister YouTube video, the clear difficulty drops significantly.
