After Boyfriend and King, a musical genius with long hair, have gotten into a car accident, instead of calling the police, which you should always do, they decided to settle the score by having a rap battle between them, and this is what you are joining in them right now on the songs of this full week:
Stand up to the King and defeat him!
After choosing between the story mode and free play mode, you have to give it your best to reach the end of the songs by playing all their notes, which is when you win. To do this, when arrow symbols above BF match, press the identical arrow keys from the keyboard.
Once you’ve reached the song’s conclusion and the progress bar is tilted towards you, you won, but if you miss hitting too many of the notes in a row, you lose and have to start again from scratch, so focus not to let it happen. Enjoy!
