Found bug with keybindings , i prefer to use Mouse middle button for USE things ! And in game a changed it but doesnt works for jumping out of copter or useing parachute ! I still have to use F , but its written mouse .... And maybe a suggestion about that to that you should use shorter text for mouse buttons beacose its not visible very well , so recommend using MMB - Middle Mouse Button ! For every mouse button. Great game by the way still needs more testing , and tweaking definitely !
