Has potential, but here is why I think it needs work:
-tiny, we don't see shit, doesn't scale up if you try using browser zoom (I tried on chrome). A lot of flash game do zoom in nicely btw.
-when your plane is on fire, you kinda lose where it's pointing, because of smoke (too much, too opaque)
-the flight physic isn't really of a plane, feel more like I'm piloting a missile with no wings, falls like a brick.
-the player plane floats on water, but ennemies crash and dies on impact. OP
