I don't know if it's necessary to create brand-new tutorials specifically for this game jam, but here's some existing tutorials and a tiny bit of advice
Godot has an existing topic in its documentation for exporting Godot games to (most) supported platforms: https://docs.godotengine.org/en/stable/tutorials/export/exporting_projects.html. There's also some documentation specifically on exporting web builds: https://docs.godotengine.org/en/stable/tutorials/export/exporting_for_web.html. It's important to note that the .NET version of Godot cannot export web builds. Not sure if it'll help, since some people probably aren't very fond of reading, but it's still relatively simple to understand and kind of easy to skim read. For those who don't understand English, there is a selection of other languages to choose from, though I'm not really guaranteeing that it'll be up-to-date and factually correct, as there are literal paragraphs of untranslated text in several languages.
Exporting games made with Pygame for the web (as far as i know) requires Pygbag, which is currently experimental. It does work, but it requires you to change quite a few things in your own game's code, which slows down the creation of a web build quite a bit. In case it matters, the last release of Pygbag was released in February of 2026 (according to pypi.org) and the last commit was pushed in March of 2026 (according to the GitHub page for Pygbag). There's an official tutorial for using Pygbag found here: https://pygame-web.github.io/wiki/pygbag/
After creating your web build, it's important to make sure that the HTML file in your exported build's directory is named "index.html". This is to make sure that itch.io knows which HTML file to load in first and doesn't freak out. See "https://itch.io/docs/creators/html5" for a more detailed explanation written by people that are smarter than me.
(i haven't really used other frameworks, game engines, or programming languages for making games yet. hope this will be sufficient.)
