What are the usage rights for these assets? I don't see a license listed or described anywhere. Are they commercial free as well as purchase free?

Basically I want to use them at least for placeholders in my current project in Godot, but I'm worried I might not have time to make final art or will forget where something comes from. To that end I'm making sure that every asset I use as a placeholder is commercially free to use. I might end up shipping with your assets, especially since they look great.

So that's my other thought. I really like them. Once I add them to my library I was hoping to use them in a future project deliberately even if I do manage to make original art for this project to replace them with. But I am hoping to sell my games

So anyway, just wondering.
