This game is difficult. Even if I stay still, the asteroids move hella fast, so I'd suggest slowing it down a little.
As for the visuals, glow is kinda overused IMO but that doesn't mean it won't work, the graphics is nice. One small issue though: if you're going pixel art, I might recommend making the pixel size consistent.
I might be a little hasrh, but nonetheless you did a great job!
