Nice title screen! 
Really enjoyable, if simple, game too.... I liked the graphical touches that set it apart from other Asteroids games. From the ship itself being a little more detailed than usual.... to the little PaintShopPro-ish "spray paint tool" ion gas clouds (I guess....) thrusting out from the ship's engines.... and especially the nifty effect when you either break up a bit asteroid into chunks or destroy the final, smallest pieces... really nice little "poof."
My own criticism, in fact, would be that your ship has way too much of everything... if it's going to have as effective a gun (I mean, it can not only go off screen and come back on from the connecting point... but the bullets/whatever pretty much can reach back to the ship itself... PLUS the powerups are godly... I got a 8-shot in level 2, and twice in level 3 a 360 degree 1-time clear-out thingie... and then in level 4 or 5 a really nifty "wave beam" a la Metroid)....... then surely either the thrust/turning should be a bit slower so you can't get out of the way or blast your way out of ANY situation.... or else you should die on one hit, just like in the original Asteroids. I mean, great firepower + decent maneuvering ability + shields/armour.... = way too easy!
But fun, nevertheless.
