I've written a level editor so far and defined most of the classes.  Only need to put everything together and draw a few dozen images.

I've finished the first level of the game.  I would appreciate feedback.  Also if anyone should look at my code, please feel free to comment and advise.

P.S.
Please excuse the amateur pixel art.  I'm a programmer (also amateur), not an artist.

I've made a few minor changes.  I've also added some theme music.  I don't know if it works.  I think there's something wrong with my computer, not the code.  Once again, excuse the amateur composing.
