Couple of recommendations
This game is great. I love that the game can be hard but then also be enjoyable for the player. But this game needs some credit fixes. 80% of the planes need purchase with real money. Only the "meh" planes are allowed to be purchased with credits that take FOREVER to save up. The original airplane game at least gave you 600ish credits per mission complete. Either lower the price of the planes or up the pay on the flight. Btw you also need to let some of the planes be credit purchase. I want to fly a boeing 747 jet aircraft without paying a huge amount of money. Thats all great game, needs some fixing though.
