Hey man I'm glad you like it! I'm re-writing it from scratch right now so I can port it to android when I finish.
The thing with the scores, is that the scoreboard is actually only local, it only saves the scores to your computer and unfortunately there is no online scoreboard so you can't see other people's scores, only previous versions of your own. When you play it the first time on your computer and see that the scoreboard is already filled out, they are just preset, as a sort of goal-making system.
I'd love to hear what your high score is though! Mine is 141080, although I'm not really sure that counts since I'm the developer :P
