Also, much less of a challenge and more so of a fun thing, I was thinking about basing the enemies off of my friend's characters from their own fnaf fangames. not outright copying them but more so its clear inspiration was taken if you know what I mean, that way they can still be their own characters and not make things messy for me and my friends I took inspiration from.

Think of the way Anart made the shades, they were based on creepypasta and while its clear when you know, they're still their own thing.

(Shade PNM was based on himself lol, and Minnie was based on Jeff the killer.)
