So this is pretty neat. I hope you the best of luck with this project. Messing around with it for a bit there were two things that stood out.
1: The GUI breaks at 2560x1440. The radar background is offset towards the center of the screen, though the other icons are about where they should be.
2: Linked blasters shouldn't shoot as fast as they do. In X-Wing and Tie Fighter linking fire didn't actually increase the rate of fire of any individual cannons, they just fired at the same time. If there's some lore justifying this I guess that's fine, though I always assumed that each cannon had a fixed individual refire rate, hence why fighters would mount multiple synchronized guns rather than a single high RoF cannon.
3: There's no way to remove keybinds. This isn't too bad, I worked around it, but it is annoying since I wanted mouse to control pitch and yaw while A and D were roll. I got this working eventually but it was finicky, and I ended up binding the roll axis to backspace in place of a proper 'null' option.
Finally I can't figure out how to host a session. Might just be disabled functionality (WIP_26) but I assume I'm supposed to be able to set a server name and password. Would've liked to give this a run with some friends.
