Real fun with a good concept, but quite hard controls with some issues.
I really like spaceship games and your entry reminded me of the pilot's test of x wing alliance where you race through rings in a space course :)
That said the mouse implementation feels a bit odd, it feels a bit like you cante really estimate how much it's going to turn related to the mouse input, maybe a more simple mouselook type control a bit like in Descent for this part could work better ?
Regardless i like the concept and i like that you even put some controls to roll left and right, the random level generation whith a seed input is also a nice thing to have :)
