Yeah, there not meant to have a score. They were just there to get the amount of high-scores up to 10 before real scores took their place. By the way, your name is now attached to your score.
Anyways, NEW VERSION TIME! I've made some improvements, which you can see below:
-Enemy ships now fly across the stage occasionally
-Four shots can now be on one screen at the same time(just like the real game)
-Difficulty goes up more slowly now
-Highscores can now be accessed from the main menu
-Score can now only be submitted once(yes, you could submit it multiple times before. )
-Editbox obscuring top score has been moved out of the visible area

Tell me if you spot any problems with this version, as I'm not quite sure I tested everything.
