Really in need of help!
Viewing post in [Devlog] see you_ SOLVED
There's a "submit game" button on the front of the My First Game Jam page. You've got to have the page finished and public to submit it, though.
Itch has a guide on posting HTML games. For a Twine game, you probably just need the HTML file unless there are external files you're referencing in your code.
Does that help?
