What is the actual license? ARR or CC0? Modrinth has ARR, while GitHub has CC0. I wish it was CC0.

I clarified it in the readme: CC0 for the code, ARR for the assets. If you need a proper licence for the assets as well, please let me know and I forward this to the artist.

I'd recommend CC-BY-SA or CC-BY-NC-SA for assets.
