I've played this game all the way through the twenty-five levels. Took awhile to complete. You have to complete one level before you can move on to the rest. There's no cheats on this game till you finish all the levels. Very challenging game. My son at the time ( seven years old) finished the levels and beat the Red Baron on the last level in two weeks.(it took me a month).The graphics are easy and not as elaborate as any of the Microsoft Combat Flight simulator games, but The colors are good, and the plane detail is simple. Still a challenge to fly and to defeat the German enemy. Make sure you run it on the recommended windows operating sytem, I tried it on windows 2000 and it didn't work at all.
