Hi there, thanks for your message !
And thanks for your kind words, it means a lot ❤️
To answer your question, yes absolutely. Feel free to use any of my music/sfx in any way you like, on any game you like!
And in terms of credit, it’s completely up to you. Once you purchase any of my sounds, think of them as yours to use as you please. There is no obligation for giving credit, but if you want to that would be great also 😊
Thanks again for your message and take care,
Joel
