I Like Lasers

Arcade-y game I threw together in about an hour. 
The music is taken from the album Output by Linde, which I'm not sure is available anymore?

Arrow keys to move (even though in-game it says WASD), mouse to aim, and left mouse button to LASER.
You can wrap around the screen if you feel like it.
Get touched by monsters too many times, and your game is over.
High scores aren't saved anywhere.
