The category rules state that you must start the run with no powerups. However, in keeping with the title of the category, the current world record run uses the bubble powerup. Therefore, I am submitting both a run without powerups, like the rules state, as well as one using the bubble.

The no powerups run starts a little after 0:50 in the video.

The bubble run starts a little after 1:52 in the video.
