Hi!
I get a little confused with these licenses. In this pack you can:
- Use freely in your commercial or non-commercial games
- Edit the sound to better fit your project
- It is not necessary to attribute credits but I would be very happy if you did.
The only thing I wouldn't like is to resell the files, for example, create a sound effects package with that same sound and sell them, or distribute them without going through that itch link.
Hope this answers your question, thanks!
