I finally got my copy of Dearly Stars, exactly 5 months ago from today when I pre-ordered it from Play-Asia (**** you, PA, for completely botching my order).
Could someone help me figure out what exactly does the panel system do (the one where you have to insert some colored blocks against the lyrics of the song)? I reckon it has something to do with the choreography of the TV performance, but is it a must to do or can I leave it to the game to decide for me?
