This is a great twist on a classic gameplay concept! The sounds are super effective, and the puzzled difficult yet rewarding. There were a couple of times i died to an asteroid that had already faded out (or was 1% opacity) which was painful. I didn't count what level it was, but I finished a level by going outside around instead of through the asteroid path :)
great work! I also love the theming of an asteroid gaining sentience and threatening us lol
