itch.io

I figured it out when you unzip the file mac uses Archive Utility as default which for some reason breaks it. Right-click the zip file and open it with Unarchiver.app and then it should work hopefully.

Try right clicking it and then click on open. 

Oh thanks for informing I'll look into it. Sorry for the inconvenience. 

I have created a standalone application and you are right, I cannot really export the model with gltf but only while running it in editor. You can check the application folder in my github projects. (It is still in development when I stopped developing it due to academic stuff)
