Hi! These are really awesome and I would like to use them in my game! It's about an archivist who tries to solve a mystery in a mansion and I think your assets fit pretty well. I don't know if I'll get the chance to publish it on Steam, but I'll definitely put your name in the Credits. They are free to use them, right? I won't modify them, maybe I'll darken them a little but in Godot (where i'm building my game). Thanks!
