How does that work?

People make rooms and you can join them, like the way audition works. Except if you don't have the song you'll have to download the beatmap first. You can join while people are playing and wait for them to finish. but I think they usually change songs so yeah ahahah

and u get points? interesting.. keke but I only ever played the Totoro song xD

yep ahhaah I signed onto the old account and I'm already level 24. I've played that much before!!

I suck ass at that game...

Too bad they don't a lot of new songs =(

here's an example

You didn't win, nub

makes me want to play again
