This game had a guy in a parachute falling down and the objective was to help him avoid all the hazards such as planes and birds
It had the same music looping in the background, with the scale of the music changing after every loop
This is the game I am talking about:
Surprisingly I can't find the name of the tune with a google search about the game, but I think I've heard it in other places so I'm sure it's a popular one
What is the name of the background tune?
