All good! kulor is fine with it as well as long as he's credited as the composer. Here is his site, if you can link it too: http://kulor.arnoldascher.com/
In any case, good luck! Feel free to post your game here once it's ready to be shown ^^
Ah thanks, I'd rather "BE Witches" appears is in the credits yeah, even if there's no link.
I'm sure a bunch of people heard the BE Witches songs through kulor's soundcloud without ever checking out the game itself!
