Very WIP! Might add more content soon!
Update 0.2: Fixed You died! sign breaking
this is a really cool project, but can you please increase the speed of the projectile and change its color? Its quite hard to see on the background.
Very nice! I agree that it could be a bit faster, but otherwise it's neat.
I think it would be cool if the larger the asteroid, the more damage it would cause and the more hits it would take to destroy, and each hit would make it smaller until it disappeared completely. Still, I like it. 
Good project!
What's up with that "pew" sound? nevermind, the sound is replaced
Is it intentionally mobile-friendly?
Also, you could have made the projectiles faster too!
Last thing, we need a score feature!
Update 0.3:
Fixed the direction problem
Added Gold Asteroids, has a 10% chance and gives you more score
