Package: Simple Traps
I see you're giving attribution to the authors of the source textures in your README, but CC BY-SA has a couple of requirements about how to do it: https://creativecommons.org/licenses/by-sa/3.0/
I am not a lawyer, but I believe you can comply properly with the license by adding the copyright notice and disclaimer, as well as some variant of https://creativecommons.org/choose/non-web-popup?license_code=by-sa&jurisdiction=&version=3.0&lang=en as well.
Fixed (at least I think so)
I believe that's fine, can you update your package's README with that as well? I'll approve after that.
