Ok this is my first post on the forums, and i just gotta ask this simple question, which is the subject. Why does that happen? I've been playing Osu for 1 year and 2 months and gotten around to playing 5 stars, and after playing ar 10.3 everything seems fine but then i do ar 9 after the 10.3 beatmap It's really hard, why? Is it something to do with our brain or..? Yeah just wanted to know this.
