Riders of the apocalypse

Riders of the apocalypse is a racing game, but instead of racing for fun, you're racing for your life.  Fend off an ever growing horde of zombies with naught but a bow and horse drawn chariot.

Can you survive long enough to be rescued, or will you become one with the horde?

look out for hay that may appear, as it will heal you if you drive over it

Controls:

W - accelerate (The chariot is always moving, this just raises your speed)

A/D - steer left/right

S - Decelerate

Click anywhere to fire

Phone:

Warning in advance: the phone controls are a bit janky as this is my first time trying to set up phone controls. 

The controls are the same, but WASD are on screen buttons.
