This game has a lot of promise and I'm glad you're leaning more into the simulator angle with it, I think that differentiates it from the other AC-likes out there. I love that you actually have visible hardpoints and loadouts like with an aircraft, that alone makes it pretty unique.
It's a bit hard to control, and as others have said the inertia is really intense, it kind of makes it feel like there's low gravity. Regaining control after accelerating forward for awhile is hard, but it's also slow enough that I find it enjoyable.
Combat is difficult and it's hard to hit things from so far away, but that's to be expected with the less arcade-y gunplay. It'd be nice to have a few more indicators that my shots are landing though.
also the death screen being just "It's over..." made me laugh
