Ken's Artillery 2

[SierraKen]

This game was originally a very old early 80's (or so) DOS or Apple game. Microsoft used it to adapt it to their own QBasic game called Gorilla, throwing bananas instead of launching cannonballs. Today I added some features to my own version I made a couple years ago. The object of the game is to beat the computer by hitting its cannon 5 times in any level. Each level has a different sized mountain and color. If you hit him 5 times you advance to the next level. There is no ending to the game and after each level your score goes back to 0 but your Level does add up. To play, you type in a power of the cannonball and the angle. The wind also changes per turn so keep an eye on that to adjust your power and angle. B+ helped me on my original one with the math part of it so I have his name in the title as well. There's no added files. The computer has a small A.I. being almost as smart as you are in your turns (sorta), but don't ask me how I made it because I don't remember LOL.

'I've always wanted to make this game ever since I started programming in the 80's.
'This was created by Ken G. with much help from others below.
'Thank you to B+ for much of the math code.
'It takes the computer a little time to learn how to hit your base.
'Created on June 26, 2019.
'Version 2 made on April 30, 2022.
'Added: Levels, random colored mountains, and better looking cannons.
