Use the Arrow keys to move around. After you score a touchdown I would recommend you stop holding down the arrow keys, or you will go right into the next guy and lose a life. Good luck!
Thanks ForceOhio. I added a high score and changed the tries left to lives. Updates: Nov. 10 2015: Deleted high score because it doesn't work on remixed projects Nov 9 2015: Made harder by changing lives to 1 and defenders move around more. Also changed touchdown look. Shared Mar 28 2015
