Well, that's one way to skip having to design menus… the game asks you for all the choices right at the command line. The first question is the wait time, the second the AI rank (99 is hardest), then the next two questions ask which of the two players you want, followed by a question about AI vs player, player vs player... etc, and lastly, whether you want to use EGA graphics.
Controls are Arrow keys, plus _ and / for one character, and T,F,H,B and X and Z for the other. This is just a trial version of the final game, which supposedly had 6 characters.
