simplified starfire... yay!
only thing I could think of as I went past the 'giant ships' in background was 'this is like starfire' but that's alright, I know it wasn't intentional (and it's not a bad thing either, was an awesome game)
I am however having to take off 1 star for collision detection. because as far as I can tell your ship is about 2 times wide as what it looks like. normally this isn't a problem... but in a SHMUP that little bit of difference can be VERY annoying.
everything else is very nice however and does flow well together.
