It would be nice to see a license, might I suggest Creative Commons by association 4.0 https://creativecommons.org/licenses/by/4.0/
I'd like to read into it a bit more but you're free to do as you please with the assets...
I've added a licence (CC BY 4.0)!
Wouldn't "credit appreciated but not necessary" be CC0? BY/Attribution does require credit without exception.
Ah! Yes is would…I will change that!
I've amended the licence so that it's CC-0!
