Both the .tar.gz and .zip Linux binaries (x86-64) are essentially the same. Download which ever you prefer and decompress the former with
tar -zxvf pmgame-1.1.0-linux.tar.gz
or the latter with
unzip pmgame-1.1.0-linux.zip
Start playing with ./pmgame in the unzipped directory, or take a look at the README.txt file that provides additional installation/uninstallation information. Try running with the --help option for more help information.
