Sure thing. It'll be in soon. Real soon.
Might need some tweaking though so I'll be happy to get more feedback from you when the time comes :)

Hellooooo

I've added Mouse aiming...

You can tweak sensitivity in the pause menu (press enter during gameplay, go to Sensitivity.

Hit Enter until it reaches the desired level. It'll reset back to zero after Max)

Also you can use the Right shift to fire, but I think once you start using mouse, you probably won't need to bother with that option anymore.
