I like it, its like asteroids but you are only worried about keeping the probe safe. Some places that I think need the most improvement are as follows:

The fact that you can start the game and already be on a meteor, you may want to prevent them from spawning on the player.
The alert box telling you the final score feels annoying and unnecessary since the score is still visible in the game itself.
Sometimes I was hit when the meteor was close to my probe, other times I was not hit when it passed through the corner of my probe. A more clear hit box would be nice.
I could not figure out how to move for the first 4 plays (1 of those plays a meteor spawned on the probe)

Otherwise I had fun, my high score is 18!
