Pullback chicken

[How to Play]
-How to operate the pull-back car
Grab a car with a touch, I moved toward the back. Not proceed when pulled back, and not turn the tire on the ground to set up!

I thought that was the mainspring wound up,
I will put your finger gently on the ground.

My car will move forward only minutes mainspring is wound.

· Let's stop the car!
Touch anywhere on the screen so good, braking the car.
Since you can not apply the brakes only once, please note, however.

Can you be the perfect stop sign in the front wheel cliff?
