Slashball is Aardvark-80's (formerly Aardvark Technical Services) first Coco arcade style game; everything else they had done up to this point was adventure games. Like their adventure games, this early effort was written entirely in BASIC. The game is basically you throwing up 1 of 2 deflector barriers to steer the ball; when you hit the appropriate key it immediately puts up a deflector of that orientation. Your object is to direct the ball to hit the center target in as few deflector moves as possible. Everything is done with text characters (except the target which is a semigraphics color bar), and is deceptively hard. Especially on later levels, as your previous deflectors stay on the screen from the previous level, making the gameplay area more and more crowed with things to deflect the ball. I believe that this is an original game.
