Hi, yes you can use it in any commercial game and publish it wherever you want, and you don’t have to give me credit. It literally says so in the first sentence of the page
This music pack contains five combat/action music tracks you can use for free in both commercial and non-commercial games, with no attribution required.
The only limitation is that you can’t re-sell it. If you’re using it in your game, you can do whatever you want with it, without giving credit :)
