Great idea! Was alot more fun when I figured out the controls. I agree with @Erockandroll that the controls need to either be the higher up in the description or in the game itself.

My only recommendation would be to put your controls at the top of your game page. It took me a while to figure out I could Accelerate and Decelerate with S and W. (Game became a lot easier once I figured that out.) 

I like this. I tried Easy mode and then Hard mode and had fun with both.
