Bloom is a bit too harsh. I also felt that the sun is a bit too fast. After hitting about 3 asteroids and having them slow my progress to stop, the sun was able to catch up to me. This happened around the 80km mark. Also, the black holes are so deadly! When trying to outrun the sun it's nearly impossible to avoid them since you need to go so fast. One hit and i was at like 20% health, and hitting another asteroid would have immediately been a game over.
I would have liked to see some shaking/extra particles when you hit a asteroid. Also, when you start going fast, I would have liked to see the camera "trying to catch up to the ship." This could be done by having the camera slightly further behind the ship, or to really sell it, add a small bit of motion blur. There isn't a good sense of "going fast", which I definitely would have liked to see (e.g. streaks of speed).
Overall, a solid game.
