I looked at what FMOD calls are made and found that if they all receive a return value of 0 (with one otherwise trivial exception) the game runs fine (without any audio, of course). It's still fun to play and I've reached chapter 5 already.
So my question is if you would consider adding something like a '-noaudio' flag that disables those calls and allows the game to run on platforms that don't have FMOD studio libraries available? We *BSDs and other potential future platforms without FMOD libs would be grateful :)
