The input manager system is fully setup, at the top-right corner of the
screen, it shows your inputs. A or Enter adds your input, and B or
Escape or Backspace removes your input. There is however, one VERY
IMPORTANT limitation of Unity's input system: you cannot disconnect or
connect input while in-game. It really, really sucks, but it is just a
limitation we have to face. Unity has a very poor input API. On the plus
side, I'm ready to start hooking up these new inputs with functions, to
make this a truly multiplayer game.
