King Slime Boss

Hello,I'm going to use your game assets in my action game, which can be found at 

https://quantnull.itch.io/realm-of-echoes

 Thank you for providing these resources!

Can I modify it for my game?

I love how the crown bounces up and down off its top :)

So is it CC0?

If yes, you should add the license into metadata for the asset packs:

"Edit asset pack->Metadata->Release Info->License for assets" It will increase the size of audience that will be able to find your art
