Quite a dynamic game with various enemy types to shoot at! I loved the music and graphics. The paralax background with all those colors looks amazing.
The asteroids also being able to kill enemies was a nice addition! I mean, I'm definetely not complaining about getting some powerups from some asteroid kills hahaha!
I didn't last too long though... I think I need to get better at dodging, as my AI co-pilot said.
One thing I think would be a great feature to have would be persistent powerups. I might have died before they started appearing, but it would be nice to have a tiny persistent speed boost, or firing speed persistent boost and that kind of stuff.
Anyway, amazing work! Have a good one :D
