Scoring: Roughly ten points per second awarded for staying alive on the road. Control: Speed up and slow down by pressing up or down on the joystick. Left/Right to Move Damage: Your car will change colors as it takes damage. When it's red, you're almost done. There is a gas gauge at the top left of the screen. As the fuel bar decreases, it will change from green to yellow to red... if you run out of fuel, the game ends. Rain: When it's raining, your car will skid a bit when moving. Day/Night Progression: The sun will rise and set 8 times during the game, after which it will roll over to day 1 and traffic patterns will repeat. Refueling: The gas gauge will flash with the road sign when you're low on gas, and there is an actual road sign on the right side of the road that you'll have to run into to enter the station. It's designed to be a little difficult to enter the station - you may have to stay on the side of the road for a few seconds sometimes to enter. The workbench at the gas station shows "closed" if your car has only minor damage When you're in the gas station/pit stop screen, move your car over the gas pump on the lower right to fill your tank, and move your car to the workbench on the left side of the screen to repair the damage to your car. When you're done, drive off the top of the screen to re-enter the roadway. You will lose points while you're in the gas station - you'll want to repair your car and fill 'er up as fast as you can. When you run out of gas, the car stops on the road and "Empty" shows up on the screen. Press down on the joystick to get back to the title screen. Difficulty Switches B/W switch - color mode - oncoming traffic moves at normal speed - b/w mode - oncoming traffic will move twice as fast Left Difficulty switch - B - normal damage - A - your car takes 3 times as much damage with each hit. This definitely encourages defensive driving. ;) Right Difficulty switch - B - Normal Workbench operation - A - Workbench will only be open when you are VERY low on gasoline. You'll have to time it just right. Hint: time how long it takes for you to run out of gas when you get down to one bar left. When there is one bar on the screen, you'll have to wait about 1/2 the time it takes before you run out. This definitely adds a level of challenge - timing is everything!
