Good sync, the game ran very smooth here with no glitches at all, the particle routine looks very capable of producing some nice results too, I agree with Benny about the movement of the ship, it seems a bit restrictive that you can't roll 360 degrees or loop the loop! Adding these would certainly help the game.
I tend to favour controls where the Y movement keys are reversed, ie. press up to put nose down, down for nose up, this is because I played a lot of flight sims on the Amiga probably.. Some people prefer it the way you have it, so an option to switch would be great.
It needs some sort of map too, something similar to the map in Elite would work well with this type of game.
The thing that really niggled me was the exhaust particles, they look wrong and just seem to float around, you'd be better either losing them completely or speedint them up 10 times as fast, they destroy the perception of speed at the moment and are too dense, same with the shot when you fire it, it's completely over the top

Normally a good thing, but maybe in this case better to be confined to when you hit something?
All in all, looks promising
