Hi,
I'm sorry but I get another error (terminal output):
"Build.x86_64: error while loading shared libraries: UnityPlayer.so: cannot open shared object file: No such file or directory"
It would be better if you directly take all contents of your game build directory and package them together, since all files created by Unity Editor, at compile time, outside "Build_Data" dir. , are always needed (I've used Unity Editor too in the past).
Thank you anyway
