In which last month, Youtube user The Gamer 540, attempts an Any% speedrun towards reaching the end of Chapter 1, focusing entirely on Middle-difficulty charts with the CHARGE decryption style (although later on, the HARMONY one) engaged in order to gain higher amounts of Battery, which will then only be used to unlock story-related nodes in the Node Flowchart. All purely for the fun of it.

Not even rhythm games (moreso, those with a followable storyline) are safe from being ultimately speedran, at this point.
