Unfortunately the Mono version of Godot doesn't support web builds yet. We figured that out a bit too late into the development. I am going to try rebuilding it for Wayland in the coming days and then I'll be able to reply with a download link.
If you didn't write c# code, then you can install the other version of the godot engine to export the game. This happened to us as well! Fortunatly, we only used gdscript
Yeah, but unfortunately we have plenty of C# in there. I don't think we have the energy for a full rewrite left after this weekend, at least not anytime soon :/
