I'd also like to know this because turns out that downloads don't work if SharedArrayBuffer support is enabled (which I needed to enable for the web version to work since I used Godot 4) so creating another page could help circumvent this issue.

@Flyce_9998 if there was a technical issue during exporting preventing your game to be played, you can submit the fix (just point out it is the original submission, just with that technical fix). You can do this on the same game page.
@SaitoInteractive Just make sure there's a way to play the original submission from the game page you submitted as part of the challenge; it can be a link to an external website or a link to another itch.io page (although that second option might get confusing for the reviewers)
