The grinding was especially horrendous, even if I understand, its probably just an attempt to coax people into getting the in-game purchases to speed the entire things up.
The physics is what I remembered to be mostly similar to the PC-version—glide bombs have higher range the faster and higher you are, missiles actually track and lead their targets, etc. making it relatively the most realistic air combat game with missiles on android.
The gameplay's a very watered down version of the PC SF2, you start and is immediately spawned in the air, you then just fly straight to get close enough to the enemies to fire whatever missile you have on hand, then you wrestle your phone trying to get a gun kill on the rest of the enemy that you run out of missiles for.
Repeat that for what could probably a hundred thousand times to get skill points and enough in-game money to spend on the actual fighter jets you wanted.
