Finally here it is, Heritage linux version for 32 and 64 bits :) The game is compressed as a .zip file. There's no need to install anything, it's the full game just run it. It has both executables, for 32 bits (x86) and 64 bits (x64). We couldn't test it as we would like as we don't run on linux, only Juan has a PC running an Ubutntu based distro called Guadalinex and it worked just fine.
Doesnt work
Depends of you linux distro, in some distro's you need additional libraries that you can download from your repository.
