Updated! 6/4/17

Updated the game, now you can beat level 3 (it doesn't indefinitely pause movement). I added a global score too, and gave some values to bosses and asteroids and enemy ships...

Also, I added mouse_direction to the lasers, so you don't necessarily have to just shoot things in front of you. Going to invent some enemies and bosses that come at you from the rear I think.

Let me know if you have clever ideas about what else I should include.
