Crosswalk Scratch

Danger!
There are turtles, sometimes boys, trying to cross the road. 
Control the car with scratch like DJ and let them pass safely.

However, the point is not determined by the number of turtles or boys crossing the road, 
but by the number of cars passing the road.

Pass as many cars as possible and get high scores.

You may be able to hurry the turtle or go through a car by polishing the scratch technique.
