I know this was just a simple game you created over the weekend, but looking past that I can see a lot of potential in this game.
What do you think about changing it from falling to flying and changing the character to some kind of superhero. You could avoid obstacles and save people to collect points or something. Keep the basic mechanic of the fall that you have and work on changing the artwork and you could have good potential for a browser game or even a mobile game if you worked on it long enough.
