Pretty Cool and Simple game mechanics!
Music sounds cool, reminds me of Ace Combat Series or Sega Genesis's Thunder Force IV. Btw, if you ever need music, you can always contact me!
I like the physics of the planes especially when decelerating and making a circle.
I also love the physics of when the missiles follow the player.
It got a bit difficult when many missiles started spawning, but still really fun.
I would play this game longer if I had more time.
Thanks for making this game!
