I've put builds up on github for each of the platforms, so anybody can try them. I'm aware there's still a few bugs, and the OSX build doesn't work right now due to the resource path stuff (working on it...).
I've included the shareware wad, but the music is disabled for that due to the license. If you have any official DOOM or DOOM2 wad then they should work and will be fully featured. Theoretically other doom engine games (hexen?) should work too, although I haven't tested. Also any unofficial wads compatible with vanilla doom should work.
Controller or kb+m for input. ctrl+f for fullscreen. Shout if you have any issues/feedback
