Very fun subversion of asteroids!
I like how it's momentum based, that's a shame you didn't roll with it further. It would feel amazing if you needed to dash through enemies by clicking right before the collision, which would give you bonus fuel and momentum. The fact that you stop abruptly everytime you hit something is a little disappointing.
Also, while the original asteroids thrived in simplicity, this game not having even splitting obstacles feels a little too simple.
Still, a very nice job :)
