I uploaded a Mac build, please give it a try and let me know how it goes. The game engine gave me this warning, but having never used a Mac, I'm not really sure what this means. I'm assuming it's the anti-malware built-in? If so, please let me know if it prompts you at all.
That was a very good idea to run it through terminal, it looks as if the game isn't registering any of the files. I don't know much about Mac but I'll try to get this working. I'm going to make another build that will force all of the assets to load. If this doesn't work, see if any antivirus may be interfering with it.
I'll send another reply after I upload the build, thank you for your patience!
