Thanks for playing and the video.
Beside game over screen I see other stuff not working too in your recording. I'll look into how Wine and Unity interact and if it can be fixed.
To be clear, when you started the game, was main menu visible?
Planes crashing is AI issue, I forgot to program them to avoid clouds (they avoid ground already).
By stabilization you mean camera movement?
I'm still building core mechanics, so there's no concrete goal beside finishin that yet. But since it's playable enough I wanted to see how people fly and shoot without my own assumptions about the game.
