I’m enjoying the graphics and smooth game play, but I have no clue what my objective is at each level. Sometimes I think I need to land or take off x amount of planes, but when I do, it’s game over. I’m at level 11 and don’t know how to beat it. If the game keeps telling me I lost when I don’t know why, we’ll, maybe it’s time to move on. Too bad, first levels were fun.
