I was getting the error
"./ExeLinux: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory"
when I tried to run the game. I noticed there was no libpng12.so.0 file so I renamed libpng12.so.0.54.0 to libpng12.so.0
That fixed it, the game runs for me now. I'm just posting this in case anyone else has the same problem.
