Ok some more feedback.
Installation works now but it complains about a missing executable. So maybe you would like to provide a small sh script. On arch linux you find love 1.0 in the aur (https://aur.archlinux.org/packages/love10/) .
After installing this you can currently start the game by just open the directory in a commandline and type love10 ./Metanet\ Hunter\ CD.love
Now comes the interesting question what is cd mode in the settings and does it work on linux ?
