In City Run, you are a street kid trying to get through each city block! Your character is dressed in red, and you are moving from left to right on the screen. Use the left and right arrow keys on your keyboard to make your character run back and forth. However, you can't just hold a key down and make him run. You have to hit the key repeatedly to make the character keep running. If you stop pushing, he stops running. The bar at the bottom of the screen shows you how much momentum he has. Push the space bar to jump over trash cans, oil slicks, and other dangers.
