It needs instructions
Well, first I want to say that it can be a really be a fun game, but not without instructions. The instructions are:
When you see the red and green lights, wait until the green lights light up. Press spacebar as soon as you can, and the race begins. You can steer only to the left. (Counterclockwise) If you press the spacebar, you steer to the left. If you let it go, you go forward. If you touch the inner green part, you lose immediately. The goal is to be the first to finish the four laps.
Now for the review: The game mechanism is quite good, but you really need to put more stuff in the game. If you win the race, there is no motivation to continue, because you don't unlock more stuff and the only thing you hear is a quiet ''bwo-bwa''. Also the background is way too simple. The whole track is made out of only three colors. And to save your highscores, you need to play it on another site, and make an account there.
I really hope you can put instructions in the game and improve these things, because the game mechanism is good.
