I liked it, it was original, and the pixel art was charming. It would have been cool to see more ship. The only problem was that I didn't know when I could shoot. I was thinking a charge up for the lazer beam, and maybe full auto for the one and two gun ships.
Overall fun game, with some tweaks you could make to the controls.
I would appreciate it if you could take a look at my submission, if you don't mind. (:
