Been waiting a while.
It looks like a decent platformer, it would just be a lot better if he died a little slower. So every time he died you saw how and then it went back to the menu where it says "How sad... You died". A little more detail would be nice. Whenever I draw something in flash that I'm not so sure of, I look it up on Google first to make it look more realistic, like the moon, for example. Not that it's necessary for this game, I just thought it might have some use to other people.
And add a boss, THAT, would be funny.
