Cheats
Each letter of the word wings on the main menu does something. To access them hold down 'CTRL', 'L SHIFT', and 'L ALT' while holding down the right mouse button. Keep holding the keys and the right mouse button and click on the letters with the left mouse button.
"W"__________________________________Music on/off
"I"_______Turns caps lock into an autofire button
"N"____________________________Skip flight school
"G"_________________________________________Guess
"S"______________Save game without having to exit
To access the cheat mode you have to go to flight school. To get an awesome pilot click on the bullseye on the airplane at the top of the flight school menu. The screen will either flash or you will get a requester asking if you want to quit (say no). Then create a new pilot with the name "Orca The Killer Tomato" type as it's printed. Orca doesn't need school. To access a menu option (much of which is no longer useful or active) create a new pilot and name him " Who is The Riddler". Make sure to put the two spaces before the name. Don't use the 'RETURN' key to enter it, hit the 'ESC' key instead. Now follow the prompts.
Tips
BALLOON BUSTING: The first thing to do in Balloon Busting missions is to take out the AA gun. It isn't too hard so give it a try.
DOG FIGHTS: When involved in a dog fight with other planes always attack from above. This is because if you attack from below the other plane will climb which is very annoying. By attacking from above you drive the other plane down rather than up.
BEING TAILED: When you are being tailed hold the joystick to the bottom-right. You should turn off to the right and out of the other planes line of fire.
As for the graphics, they are truly great. Nice pixel-art for sure. The music and sound effects are also good, which helps creating the perfect atmosphere for this kind of game.
Another thing I enjoyed about Wings was the storyline. You play the role of a character in the Great War, and there is a diary of your life at the base and the events you are a part of. Excellent stuff.
All in all, Wings is a great game. I would recommend it to anyone, also those who are not generally interested in flight simulators.
