Moving and destroying asteroids feels nice, but the game really could use some sounds and music. Also, the difficulty doesn't seem to progress, once you get a hang of how to destroy asteroids, you basically can't lose. maybe you could make it that more asteroids spawn the longer you play, or they become bigger and need more bullets, or maybe when you destroy them they will split into several smaller ones (literally have seen this idea on this very jam in another asteroid-like game). this would make it much more interesting. otherwise, good job, I liked it
