Out of curiosity, is it possible to use assets that are Free for Personal and Commercial uses under a Creative Commons Attribution 4.0 International License?
Technically, it's not public domain, but also not paid assets so... I just want to make sure.
I got a couple hundreds soundtracks under a CCA4.0i license.
Otherwise, I might have to plan 1 out of the 10 days for producing my own soundtracks. Hahaha!
