The game doesn't compile... I downloaded it to check what all errors you had. Just to name a few: You reference a method you haven't written (or the method you did write isn't accessible) and there are some runtime errors as well. If you need help correcting them, you can always ask on the forums.

I almost forgot! Controls: Space to shoot F to fly

Heres a bug: When playing the game, if the score board has not yet loaded, and the reset button is pressed, the game will not load. If I hit reset on my browser after doing this, the game comes up with an error, BUT if I hit reset on my browser a second time, it works. I think what is wrong is that it was trying to process my score, but it didn't get to finish. Maybe you could prevent the reset button from being pressed, and add a replay button on the scoreboard screen. Just a suggestion. All in all, awesome game. Super addicting. (I think some people (*cough* super_hippo *cough*) might have played it for several days before achieving their ultimate score (no offense super_hippo))
