Hi Aegide,
To properly compete in the jam, you should provide your entry's source code as per the jam rules:
> Source code under proper open source licenses should be provided for each game
You can upload a ZIP of your project folder on itch.io, or provide a link to a version control repository, or both, as you prefer. If you don't want to share your code that's up to you of course, but then your entry won't be in the final ratings.
