When I saw the screenshots, I was expecting this to be like a "1943" arcade game clone, but what I got instead was this interesting surprise of a game! I really liked the like landscapes you were able to make with your sprites. Like, "PEARL HARBOR" , to me, looked really good, from the coastline to all the little building structures.
Dog fighting with other aircraft felt fun from a control standpoint. Really liked the tense feeling of being chased by them; having to frantically move else be peppered by their bullets if I fly in a straight line.
I like your concept of this game. My only big critique is that I feel that the enemies are both too responsive / too fast right from the get go. For example, I feel that if maybe the stationary turrets were a bit slower with turning, maybe at least initially for the first stage or two, it would give a much more forgivable learning curve. The planes already move at a relatively fast pace, so I think it may be a good balancing decision since the playing field is already skewed against you. Maybe I just suck, I did die like five times on Tutorial 1 lmao.
All in all I really did enjoy playing this. I liked you take on this type of game, and I definitely see myself wanted to play more.
Well done!
