Slide Adventure: Mag Kid

Back in the late 70s, Atari came up with the trakball controller for a little game called Football which represented the players with Xs and Os. As the video game market exploded in the 80s, the trakball was used on games such as Missile Command, Centipede, and Millipede. The trakball was essentially a big marble mounted in a receptacle with rollers underneath which mapped its X and Y position. For example, to move the cursor in Missile Command, players rolled the trakball with their palm(s) to target incoming missiles.

The Slide Adventure: Mag Kid game includes a special controller that's similar to the trakball but in reverse. Instead of rolling it with your palm, you roll the controller on a flat surface to move a creature known as Mag Kid.
