you used all of the themes and somehow turn it into nice short game with the story!
and Love the music it doesn't get bored quick.
i like the effect of stars passing by and overall art style, but i think destroying asteroids needs a bit more effects and graphics
and need some tip for how to defeat the boss because in my playthrough if I make a single mistake on the boss phase, I am good as dead and i really want to see how it ends
