"What a letdown, Sky Force could be such a good game, but you need to play again and again the same levels in order to get stars to upgrade your plane, or you have to pay. I have bought the booster to get 2x stars, but it's not enough. Grind, grind, grind, or pay, then still grind. What was once a great game is now a grind fest, money munching, shadow of its former self but with better graphics."
