I used these sprites in a game, yes. It's called Eight Stained Clues Chapter 4 (it's an interactive chapter of a 13-chapter story.) I recommend you read it before playing, just to know what's going on.
Here it is. It's told from my OC's perspective. There are also other stories which connect with ESC in that folder.
I have to say this is a non-canon crossover, as I'm going to revamp my character; she isn't a creepypasta anymore. The Aerial in this fanfic has almost nothing to do with the one of the revamp; it's like another character unrelated to fandoms. Still, I'm going to keep the fanfic on my gallery.
