I gave it a try, was flying around in circles for a while trying to hit my target, pressed space, but it didn't seem to have any effect, eventually managed to line up with it and fired off some missiles, then the game told me that my next target(I now realize I must've pressed Z along with X) is 78000 units of distance away from me, I tried flying towards it, but it was taking too long, even though I was holding shift the entire time, so I gave up.
The controls are very uncomfortable to use, I dunno if it's how they work in other flight sims, cause I never played them. Also, I had the same problem as SPECXHT, I ran the game in 640x480, windowed on Win10, Radeon RX 550. The starting scene with the hangar looked strange, too:
