From Kevin Neelands:
In this simple little diversion, all you have to do is try to prevent a little dot traveling on the screen from running into it's own trail. The longer you stall this inevitable collision the higher your score is. Really quite simple. Press START to initiate the game, then tap ANYWHERE in the playing field to force the dot to make a sharp right-hand turn before it plows into the border or the path it has left behind. The program keeps track of high scores for friendly competition.
