This was very good it's just that I have a few things that you could possibly change. You could use any other key other than the shift key due to the Stickey Keys problem. Also, I thought the controls could be a little more smooth (that just means when you stop accelerating forward). Cuz when you stop pressing the up arrow you keep going. It's just a little confusing. Those are just the couple of things that I thought you might be able to change.
I found it very easy to just sit in one spot, spin around in circles, and hold down the fire button. Ok well I thought it was very good and I know you put a lot of hard work into this. Great job!
