Ok, I finally got it.

I didn't play this game for months because the QR trick makes the game really boring, they should make a category without this glitch.

I did this bug in the first 4 moons and so I think that also a 6:2x is possible, but you have to do everything perfect, and it would be really annoying.

I also have to do the 25 moons, because the leaderboard is empty... After that, I think that I'll start Smos6e speedrunning.
