Bro, we said that a billion times; you need to go turbowarp and edit the code and costumes, then go to packager and choose HTML. If you don't know how to edit game or code, just go and learn how to code in scratch.
And to put it on itch?
Go to packager and load the project. Scroll down and choose HTML. Package the project and download it. Now just load it to itch like a normal game.
Thanks for the help I didnt understand the first time because I have never uploaded any thing on itch
