So the file libLive2DCubismCore.dylib is actually in \lib\mac-x86_64 ...And the game actually did open but seems like somehow they couldn't find the file. Maybe try copy the file ' libLive2DCubismCore.dylib' then paste it under the folder \Hicked.app\Contents\MacOS ?
Another solution is you can try to run the game using the method from the following link.... https://www.renpy.org/wiki/renpy/Mac_Launcher
