Hello Jamesac68 !
The new update is available now, the update 1.03.09032020.
The inverse control for the joysticks is available!
Sorry for the delay.
If you use your keyboard or the cross of the gamepad, you have the possibility to reverse your control.
But if you use the joystick of the gamepad it's not possible to reverse.
I can add two new options in the control menu to inverse the Up with Down and the left with right with the joystick.
