No man, you don't catch the problem.
I want to say when I change the binds, and I press enter on "save", the game looks like save the binds, I mean, on the option screen menu.
But when you finally play, the joystick binds still remains like default binds, without changes.
For the keyboard binds the problem is different:
I'm binding WASD for direction, that's work fine.
And for A and B I chose: T keyboard for A, and Y keyboard for B. The problem is Y bind don't do nothing, even if the option screen show that key was binded.
And the F11 don't do nothing men, you can check it your self, the game does nothing and still remain windowed.
I'm trying the 1.1.0 version.
