Fun until the buggies get ya.
I enjoyed it a lot, but when I was trying to jump back up to the top of my ladder after retrieving one of the invincibility power-ups, I got snagged on a corpse and couldn't move: I was just stuck in the jump animation. Oh, and I also opened the link to your site like, a dozen times. You should just put one on the game over/submit score screen, if you ask me.
Other than those two things, it was fun and animated smoothly. Keep 'em coming~
