Can you stop the alien menace?

I was going to post a screenshot, but then I decided it would be better to upload a demo instead: New Captain Ace demo.

Level transistions work, and I added a boss life bar as well. The game requires the XNA framework to play. Also, you can play it with the 360 controller if you have it (joystick moves, A or right trigger shoots). A fullscreen executable is included.

Enjoy the demo, and post your high score if you finish it(my high score is 17125).
