The Linux download currently only shows up on the Linux-mentioning news page... not even on the downloads page from there.
Although you should be able to include the Linux executable with in the same .zip as the Windows one (maybe the MacOS one too, if they're all using the same .pck file like it seems like they should).
I had to make some changes to the Linux build, so it was taken down for a day. It should be back up now! Please let me know if you have any problems getting it to run.
That's a good idea putting all the executables in one zip, it's how I like to download games, though it may be confusing to less technically proficient players.
