Thanks for the work you've put in, my dude.
I worked out a little while ago that it was probably the Leaderboard's fault, and was trying to find a way to fix it. The browser version of the game now has the leaderboard completely disabled, and that should work. It's a shame, but until I work out exactly what's going wrong, it's all I can do for now.
Thanks (:
Hey Mate,
I still can't get it to work in the frame above, but when trying to dig deeper I noticed that it works fine if I just load the page directly:
https://html.itch.zone/html/10737323/index.html
So this might be a quick fix for others still having issues.
In terms of a proper fix, understanding that it was running in an iFrame, I was able to dig a bit deeper and capture some specific errors.
There are lots, none particularly useful, but the early ones seem to be issues loading resources.
The very first error that happens is this one:
USER SCRIPT ERROR: Invalid operands 'Nil' and 'Nil' in operator '+'.
JsonLoad (res://Scenes/GameManager.gd:360)
Given this doesn't happen when you load the game directly, maybe it is related to the cross-origin policy for resources. Though I would have thought this would be a problem for all games uploaded to itch.io, so maybe that is a dead end.
Unfortunately while I know a decent amount about Javascript and HTML5, I don't know much about Godot and Web Assembly.
Hopefully this helps point you a bit closer to a fix though, or at least lets some others play by loading it directly using the link above.
