I don't use my assets on itch for Primal Planet, except for my kittens pack, but that's kind of an easter egg. It's mostly original art and then some edited versions of asset packs I bought myself from other artists :)
It will be available on Steam and the goal is to get it onto all major consoles too. You can check the game's Steam page here: https://store.steampowered.com/app/2350270/Primal_Planet/
