Ah damn, sorry about that. I'll check with the people running the jam to see what the rules are around uploading builds after the deadline. If I can I'll upload downloadable versions.
Have you been able to run any other html5 games from this jam made in Godot 4? I wonder if that's the issue.
I'd say about 50% of html5 builds work for me, and I've tried about 20-25 of them so far. Sometimes it shows some Godot error message about some web server settings.
Okay, I reached out to the admins. My suspicion is that the "SharedArrayBuffer support" setting you have to check to get Godot 4 games to run in the web is what's causing the issue. I wouldn't put it past Macs to completely disable that feature lol.
