This is simple but surprisingly very fun. The way that it randomly guides you into new challenges is clever. I'd be interested in knowing how random it really is. Is the way it moves decided at all by the proximity of the asteroids around you? Because it was good at not moving me in such a way that I couldn't stop myself from dying, apart from on a couple of occasions. I think that the bullets should be slightly bigger because I kept on missing my shots a lot. Also, I think there's a bug where the music gets louder every time you retry.
Thanks for the feedback Patrick. The ship rotates in a single direction in small random increments, while there are small random impulses to cause movement. After a random amount of time, it will switch to rotating in the opposite direction. I agree with the bullets, and wanted to go back and make them better, but ran out of time.
