Music is Awesome!
I love the concept.
Some ideas on my part:
- scrolling / zooming should change the background too
- maybe align the camera so I can see the next planet so I don't have to scroll / zoom manually
- drifting away... I'd like a reset button
- web player > not full screen: The tutorial text doesn't show
- on launch: for a while the orbit radius increases and then later the asteroid launches in a different direction
