EGA Snake

You move a snake around the the screen. Your goal is to get as many points as possible. Points are gained when eating rats. You get more points the faster the snake moves, and also when entering higher (and more difficult) levels. In the upper right corner is a watch. Why ? Well, you must eat a rat before the time is up. If you should fail to do so, that will cost you 500 points. Just before the first rat on each level appears you will see the head of the snake flash. That will come in handy from level 9 and higher because then the snake's starting point will be random.
