I have a mac. Also, it's the web version that won't run. I posted a topic about it, and one person said that in godot they had to fiddle with the settings to get it to work. I think they said the SharedArrayBuffer toggle on itch helped.
I already toggled that flag on. Otherwise I can not play the game myself (on Chrome). I will add a macOS build because that appears to be easy with Godot, but it might not work since I don’t have any tools here to test it or (officially) sign it.
