Actually I am 11 years old...I started playing when I was 9 
I did not have gmail on that time and I was not allowed to use my mom. And finally When I was 10 mom told me that I can make a Gmail account 
I make an account and Start Playing. When I did not have gmail I used to play as a guest 
WELL Osu! IS A GREAT GAME FOR ALL (When you first play it is hard You just fail. For me it took 1 month to play and practice with keyboard) I play with mouse and keyboard.
