The screenshots look nice. I tried the demo and it seems to be super early in development. This might have potential, but is still ways out.
I tried playing it with my old Thustmaster Flightstick, which I still had lying around for years unused. It is technically possible to use it, but you have to map every button by hand without much explanation, an overall it doesn't really work well. Especially the thrusters are binary, meaning the game expects you to press like W or S to accelerate/go back and you cannot map an analog slider. I know, this is still in EA, but they do not seem to have flightsticks in mind as primary control devices.
