Loved the atmosphere, narration, and in-game voicovers! I also appreciate the small variety of gun types you could switch between.
I didn't really know where hitting Q/E would send me, even after failing and retrying once, so it felt like I spent a lot of time trying to get my bearings after switching.
The limit on the guns' pitch was probably a historical accuracy choice but it definitely felt a little too limiting from a gameplay perspective, especially since the planes were hard to see from far away. Luckily I still survived the night!
The menu background art looks awesome and feels like it contrasts the picturesque setting with the tone of air raids nicely alongside the old jazz music.
