Loved the music and the bubble sounds Tom, glad you got around to adding them. I found with the perspective camera sometimes it was hard to tell if I was in the bubbles or not, and sometimes it was impossible to avoid them. My best is 187m!
I agree, it's not always easy to tell whether or not you're in a bubble column. Unfortunately using an orthographic camera makes everything look really weird. My best is 318.5m :)
