So the official FNF devs have officially added lemon demon to the game. But it is only during the Week 7 update. Oh and also there has been some updates to the past weeks. I don't what weeks but the only week I know is week 4 has a week 7 update and that's it. Oh and just a reminder if you go on the official FNF itch.io page don't post any bootleg website that have FNF because an admin on itch said that he/she would ban users for posting bootleg links. The reason behind this is because Ninjamuffin (Creator of FNF) wanted everyone to play FNF on Newgrounds.com. I will also assume that Phykro won't let a person post a bootleg link of FNF as well. I also have may found a bug but there is an instant where if your hitting notes you suddenly stop beeping  idk how this happens but its all I have figured out is that the last note you press during any segment of the song its stays there like your holding it even thought you not it's very annoying and it even happens in Phykro's itch.io port game of FNF.
