So, let's say if i am using some free asset from itch, crediting the author/provider inside the project is fine?Where can i find this license CC0 from the assets from itch
If you filter assets on Itch.io to just the free ones, you should be good. Most specify the type of license on the asset page.
Credit the asset by link, either in an About page or on your game page for Itch.io.
