I really like the art of the louse. I felt the tones were really good. It took me a bit, but I laughed when I saw the mask on him. Good job!
I think one thing that could make this game even better would be some kind of reward for the player when you hit a milestone - maybe every 2000 or so. It could be a change in the background or the objects you are dodging, or a message and a pleasing sound effect.
I did find one bug (haha). After I had gone for a little I died. I stopped, but the screen kept inching forward. It wouldn't have been a problem except the tiling of the game didn't continue, so it started scrolling off of the end. I attached a screenshot of it.
All in all, a good jam game. Great job!
