Ahhh, love me a nice top down flier.
Quite challenging too, especially the little planes are proper annoyin'.
Took me quite a few tries to pass all three missions.
If you do anything more with it, maybe some easier enemies too, for progression. And I almost got lost at sea a couple of times, maybe a wave texture here and there wouldn't be amiss.
Would love to see bombs destroy buildings and trees too, just for that extra bit of character.
