' Your mission is to hit your opponent with the exploding banana
' by varying the angle and power of your throw, taking into account
' wind speed, gravity, and the city skyline.
'
' Speed of this game is determined by the constant SPEEDCONST. If the
' program is too slow or too fast adjust the "CONST SPEEDCONST = 500" line
' below. The larger the number the faster the game will go.
'
' To run this game, press Shift+F5.

' To exit QBasic, press Alt, F, X.

' To get help on a BASIC keyword, move the cursor to the keyword and press
' F1 or click the right mouse button.
