I just updated the game with controller support for the Xbox One controller. A is jump, B is duck, right shoulder button is shoot. Basically as in Call of Duty. I've tested it on Windows 10, I'm not sure if it works on OSX or Linux. I'm also not sure if the Xbox 360 controller works the same as the Xbox One controller. Can anybody check?
Can you clarify what you find annoying about the sound effects? I want to fix that.
