I've added two additional menu options specifically to make it easier to speedrun now that there's been one official attempt/record, difficult not to get the record when you are first =D
One option is to skip the intro, because that takes up a full minute and there's nothing you can do to speed it up. The second is "Lock Cursor To Window" this is on by default, by turning it off you can, in the case of the speedrunner, vanni_van, scroll through your notes outside of the window while still actively playing the game using the keyboard or a controller.
Here is the video of the current world record for any% of Adventure of Rikka: The Cursed Kingdom =)

This patch also has a couple of minor bugfixes that was discovered during the speedrun.
