No, but it’s highly appreciated it.

If you plan to credit me, you can do it in the following way:

“Music by Lufus”

Unlimited games. (As long as you’re a small business/game studio or solo developer you can add them to unlimited games).

If you’re a big size business/studio, or AAA studio, contact me at iamlufus@gmail.com.

Yes.

If you’re only an entertainer (a.k.a. Streamer or YouTuber) and you're not the developer of the game and you are not using my music for any game developing purposes, credit is required in the description.

If you’re the developer of the game and you’re making a gameplay, game dev vlog or derivative no credit is necessary.
