Help Shrek to avoid obstacles while he rides a skateboard in the city.
First click to select your skate (there's 3 available). On the race, keep the arrow key down pressed to give power to the jump and release it to jump. While you're in the air you can use the arrow keys left/right to do some tricks; while on the ground, use the arrow key up to do them. The more tricks you do, the more points you get.
