I would def like to help too (If you couldn't tell already by me making a thread about moderation) Here's some proof that I completed the game 100%
I don't see why getting all perfects in the game casually would make one qualified for being a mod. If anyone should be a new mod I think it should be @Sundex . Although, I'm quite the veteran of the series myself, so I wouldn't mind getting mod status either.
That's not all of the same knowledge a speedrunner of this game would need, buuuut ok
I would like to apply for moderator status. I remember a time in my early days when I completed all the way to remix 8 (but that was back when I played casually). As for present day, I have a grand knowledge of all of the Rhythm Heaven games/how they are set up, even though I myself can only get so far on each of them thanks to the scenarios in which I play the game. I don't have a screenshot of my completion of Rhythm Tengoku, but I believe the information above is enough for you to consider
