This is my first time playing Project Diva (only play the demo, plannned to buy the game).
When the arrow icon shows, what button should I press? I tries (probably) all the button yet none of them are correct. For example when it shows right arrow, if I press O it will missed (worst). I try other button, but while it shows cool (or fine) it breaks the combo means I pressed the wrong button, right?
So, what should I do?
