I like the change of music when you have one life left. It's certainly a good concept that I haven't seen before, so kudos for that!
The game feels a tad luck based sometimes; it seems you don't always have time to dodge if you're already floating high and getting near the end of the rope pulling cooldown. This can make it a bit frustrating cause it didn't feel like I did something wrong. Maybe this can be fixed with a super tiny tweak to how fast asteroids appear or a bit shorter cooldown.
I'm looking forward to what you're going to add, maybe some NyanCat powerups?
Oh and one more thing: I personally don't like pulling all the way down, I prefer more frequent smaller tugs over a longer period
