The world of FNF is transferred to Hell. As in the original version, Boyfriend needs to prove his right to be with Girlfriend by defeating many antagonists. The difference in the appearance of the heroes is colossal, since each of them is now a hellish character. The rhythms of each song also picked up speed and became many times faster, which makes the gameplay difficult as hell.
In order to defeat the hellish antagonists, Boyfriend needs to perform all the songs to the last note. To do this, you need to carefully monitor the movement of the arrows on the screen, and at the moment of matching a pair of identical characters, click on the corresponding keys. Make exact clicks until the end of the music and Boyfriend will become the winner, but if the misses are repeated several times, the guy will not be able to finish the song, because it will end prematurely, and then you will have to start all over again.
