If I don't mind anyone, then I can use Scratch?

I don’t think so, unless you can find a way to natively run scratch games on itch, I doubt it. Also itch is kinda like senior scratch, similar names. Though scratch is for younger audiences and beginner codes whereas itch is for people who have graduated from scratch and moved to platforms like unity, godot, and unreal. So I don’t think you will be able to put scratch onto itch, though I could be wrong, lemme know if I helped!

You can use scratch as long as you use turbowarp to convert it to html. That way it will be playable on itch. Good luck:)
