I was not, I'm afraid! I wasn't aware it was a thing until after I was nearly finished with the game! (Now I'm curious if the logos are similar, though. LoL)
From what I've read, there are some vague similarities in some world building concepts due to both this game and Changeling the Dreaming taking inspiration from Fae folklore, but they are otherwise quite different. I admit I'm not at all familiar with that setting, so I don't know how deep the similarities really go. I just glanced at the wiki page when someone first brought it up and saw some stuff about souls that was a little similar (but not the same).
This game is more urban fantasy and deals with more than just Faeries and Changelings (though the latter are definitely a central focus.)
I don't know if it helps but someone who worked on Changeling: The Lost (which I think is related somehow?) enjoyed Changeling. (They pinged us on twitter as they were reacting to the game). I mean, I'm *terribly* biased but I think if you enjoy Fae and Changeling related things, you should give the game a try (though we're taking part in the winter sale just so you're aware!) because we really love Faerie lore and tried work a lot of it into the game in fun ways.
I don't know if this helped at all, but hopefully!
