This is really exciting. It's a shame it took this long, but it happened. In the Descent Dev Discord(zico's old server for Dxx-Rebirth), they're working on improvements. I think they've already sorted out proper aspect ratio handling.
Overload feels like Descent. Keep in mind there's a bug in the final version of the teaser where the joystick max. rotational velocity is slower than mouse.
I think this version is supposed to fix that. I know you could assign directions to the hat, but the in between directions weren't working. That is: You can slide up or left, but not up/left.
