Race 2D description

Race 2D is a classic game, and my game here is little different from it. In game, player need to control their car to avoid collision with other cars. The more road player can move, the more increased score he gets. If player's car can not avoid collision, the strength line of his car will decrease. But for each 500 points player got, strength line will be full again. The game will be over if strength line is zero.
Wish you happy playing game!!!
