Okay... After playing it here are my thoughts:
The graphics are nice and crisp. The subtle left/right scrolling of the starfield when you're moving is pretty slick. The controls are responsive and quick... with one exception. Which leads me to my crit:
Having the tilt mapped to two different buttons seems a little clunky, especially since the left shift is so close to my WASD keys. It's a little difficult to control movement and tilting and barrel rolling all with my left hand at once. If I could make one suggestion? You could probably get away with just one tilt button. Used contextually, it could make you tilt left if you're moving left, or right if you're moving right. Additionally, if you're not currently moving left or right, it could tilt in the direction you were last moving.
Just an idea.
And yeah, I'll go ahead and submit the bug.
