Hello! Another person having trouble with the Linux version (1.2.0 tarball edition). `vis/visplayer` isn't executable, which isn't a big deal. The bigger problem is that it relies on an old version of libpng (1.2) that is unavailable for my system. One option would be to update it to libpng 1.6. The other would be to bundle the shared library with your game distribution.
There may be additional libraries required -- I haven't gotten further than libpng, though.
