I have a long way to go: scrolling, powerups, music, all the regular enemy ship patterns, etc. etc.
But i wanted to get feedback on what i have so far, 10 hits kill the enemy ship.
The enemy ship follows one of two patterns and swaps between then periodically.
I get patches of jerkyness, though i think its my machine rather than the code (though i have a lot of optimisation to do anyway), i'm interested in hearing if anyone else gets it too.
Edit: it seems the link doesn't work, if you copy it then paste into the address box in IE/netscape it should work.
