Export your Godot game early enough to fix the web problems

Check the requirements for your version

Open the web-export documentation that matches your installed Godot version. Confirm the renderer and export settings supported by your target, then install the matching export templates if needed.

Pay attention to any threading, browser and hosting requirements described for that configuration. A feature working in the editor doesn't establish that it works in a web export.

Use a tiny scene for the first attempt: movement, one sound and a restart. It's easier to identify a configuration problem when the test build has only a few things to do.

Serve the exported files together

Export to a clean directory and keep the generated files together. Use a local web server for the first check instead of assuming that opening the HTML file directly reproduces hosted behavior.

Open the browser console and network panel. Look for missing files, errors and failed requests. If the export relies on particular hosting headers, verify them on the real host as well as locally.

I would publish a temporary preview before polishing the loading screen. That confirms that the actual delivery environment can run the game.

Test like a player arriving from a link

Open the link in a fresh browser session. Check the first interaction, keyboard focus and audio after user input. Resize the window, leave the tab and return, then restart the round.

If you expect mobile players, test touch controls and readability on a phone. Don't treat a desktop browser result as a mobile compatibility report.

Make one change, export again and check that the hosted version updates. A reliable release loop matters as much as the initial successful build. Once loading, controls and restart work from the shared link, you can add content with a much clearer picture of the limits you're building within.
