I have seen games like Just Dance: Disney Party have IL runs where it isn't about time but score, I think that would be a great addition especially for the people that don't want to exhaust themselves to death doing all the songs in one go, and score would mean that people actually have to play the game and not idle until the end of the song.

there isnt much to make extra speedrun content on this game so a death% would just be an extra little thing

Obviously, this game doesn't have that many category extensions to offer but one that could be a possibility is cricket%. The goal of this run is to take a picture of the cricket and get the news flash where multiple crickets show up, its nothing special but it could add more to this game's speedrun community.

The run would be to play all cutscenes.
