If the Spooky Week of Friday Night Funkin' (Week 2), features some of your favorite characters and songs, then you really are lucky, because at this moment you are invited to play an expanded version of that week, with a mod that only features the two Spooky Kids, who you will now face on more songs than before:
Let's have an even more spooky week in FNF!
After making your choice between the story mode and free play mode, in either of the two, give it your best to play all your notes according to the charts until the end of the songs to win. This means watching when arrow symbols match above BF's head, a moment when you need to press the identical arrow keys, and that is how you hit notes.
Remember that one missed note might not hurt you, but if you stack multiple of them in a row, you lose and have to start again from scratch, so be careful not to let it happen. Good luck, we wish you all the best, as per usual!
