I couldn't get into the bug reporting facility so I am leaving this here.
I'm on a Mac and running version 1.11.0. I'm using a Trooper joystick.
Changing difficulty level is now done from the player selection screen. When I use the Mac mouse to change difficulty level the game loses track of the fact that I have a joystick and it expect me to click the mouse button to continue instead of using the joystick button to continue.
I can send a video if you tell me where to send it.
Thanks,
Dan
