First impression was pretty good. I hooked up my Thrustmaster T-Flight Hotas X with ease but the control settings was a bit of a mess. It was nice to see the hotas name actually show up in the keybinds. Flying felt good with the hotas and I quickly got the feel for it and started shooting down enemy planes even when I hadn't flown in any game for quite a while. Overall I think the GUI and especially menus need a lot of work but they were obviously WIP. Plane/weapon selection was a bit confusing, I think you should redesign how it works. I think I'll put some more time in it to see if I come up with more stuff.
Keep up the good work. Oh and the game looks absolutely amazing.
