Usefulness limited without choosing a license for us! ^.^ You technically “own it”, but you can do something like give it to the “public domain” by choosing something like CC0!
I forgot! You can use it for whatever you want, commercial or not. Even if I copy and paste a license, it's truly a free file like my other files. I won't seek to claim the asset under any circumstances!
For and by the community. At the time, I was searching for my calling, and I found it, even though it's not in the Game Dev space!
