Hi, very good game!
For Linux users struggling to get it to run, you generally want the franken-linux-x86_64.tar.gz version. And you need to be sure to install dependencies: libSDL2 and libSDL2-mixer-2.0.
On Debian/Ubuntu/derivatives, that means using `sudo apt install libsdl2-mixer-2.0-0`. Look for similar packages on the other distributions.
Hope this helps. The effort will be worth it!
