Yeah I understand. I wanted to put my game on webGL to but had a last minute bug where my screen turned black in webGL.
No I didn't know about the Q option, (probably because I jumped right into the game and ignored the "how to play" button assuming I would know...) I just tried it out and its nice! A good addition would be a "look back" button for when I am driving backwards.
And thanks for making the game haha
