This mod combines two antagonists at once – Chara from Andertail and the main character of FNF Classification. In pitch darkness, you’ll see the silhouettes of the antagonists performing the song “Shrouded” against the King of Music, which you’ll play in first-person. The arrows are also not very visible in the dark, and so it won’t be easy at all to perform this song perfectly.
Be very attentive once the music starts. You need to concentrate on the symbols running upwards. They are gray and in the dark they are not very noticeable, but still you need to wait until they meet the stencils that are fixed at the very top, and at that moment press the key corresponding to them. Keep singing until the end of the song without making too many mistakes so you don’t lose.
