The Exit 19 configuration window has an input config tab.

Listed are a whole bunch of mappings for things like Jump, Crouch, Fire, etc.

I am going to assume that those are not actually in the game? Because I cannot crouch or jump.

Also, when I plug in my xbox gamepad, the game will be in forward-walk mode automatically, and never stop walking. Is that by design or is it a bug?

As of now there is no gamepad support, and yes those buttons do not actually control anything
