Having a bit of difficulty getting it to run on linux - tried both versions in command line to no avail, I get the following error talking about a missing library:
$ ./franken
./franken: error while loading shared libraries: libSDL2_mixer-2.0.so.0: cannot open shared object file: No such file or directory
unpacked from the tarball there is only the following:franken
franken.rpg
LICENSE-binary.txt
README-franken.txt
So perhaps a lib file is missing or some link is broken?
