Nyan Cat Runner

The other day a found a simple Nyan Cat game. You jumped across an endless number of floating platforms and try to get a high score. I figured something like this wouldn't be too hard to make, so  I took about an hour and a half to make this: https://dl.dropbox.com/u/150961870/Public.html

Came out ok. I basically did this just to gain a bit of experience and see what would go into it.

NOTE: The concept for this game was not my idea. I did not create Nyan Cat, or the music.
