it's amazing, it's structured like a real demo, with mini tutorial levels, which helped me learn the controls better. and it also makes me feel like there's a whole game waiting for me after the demo. The general art direction had a sense of intrigue which made me wonder about the game's setting. I've never played a plane sim before, (do all plane games control this way?) and could not beat the turrets level. Maybe there could be more visual effects indicating the plane's move direction more intuitively. Or perhaps it's supposed to be a little hard by nature, so that the players can have a journey of mastering them? Good work!!
