Hello, I'm adding this audio pack to my FOSS game engine to be used in the demo (with credits listed of course), you can check it here: ArcadeFighter
It would be nice though if you could add a formal license to your work so there is no ambiguity to the expected use of it. For the comments below, I suggest something like the WTFPL or (if the sense of humor is not of your taste) one of the Creative Commons licenses (the CC option should fit your needs).
Thanks o/
