Game fits the theme. Had a hard time figuring out if I was supposed to use the missiles to hit the beams or avoid them at first. It seemed best to avoid, and that seemed to work okay.
The gameplay is straight forward to understand and definitely ramps up in difficulty. I would suggest a splash screen or audio effect when you "lose" as it was hard to tell if I passed a level or died, or what, as every so often the ships seemed to hitch and be placed in the center again without my input.
Enjoyed the concept.

On my first attempts I struggled to get to the level with the timer and couldn't really tell if I was winning or losing. Hard to say how much time I spent on that.
I tried it again this morning and spent roughly 7-10 minutes working my way through the levels and completing the game. I'd say that's fairly reasonable in my opinion. Someone wit better reflexes and mouse control might have completed it faster.
