Here are my thoughts. though it has a nice presentation and graphics, it suffers from frustrating lag issues. Also, I found that the controls felt really tight and considering that I was having framerate issues, it's hard to steer properly without crashing constantly into walls. A Brake button would have been helpful as well. This has no sound nor music and I know you already established this. None the less, this also hurts its score.
A game like this in my opinion is obviously meant for more advenced computers considering that my laptop is rather old. I can see effort in this, but overall it deserves more of a polish.
