It was fun flying around destroying things! I'd love to destroy more!

Perhaps the rock walls could be a little more forgiving? Sometimes if I hit the rocks I instantly become "too slow" and it's game over. Other times, I just kinda bounce off and slow down, but then I can keep going. 

Really cool game! Took a bit to get the hang of it but I had a lot of fun once I did. Really like the idea, nice work!
