Wow, I really like the art you used for the game! It's very unique and I would love to see you make other games in this art style. I just noticed the small lighting bolts that come out of the Score screen when you load the game and they really do look extra cool!
I think you did a great job with player feedback as well, like adding screenshake when an asteroid explodes and your ship flashes red if you collide with the asteroid. Great job!
