Nice and tight, cool flair and polish. Smells like classic R-Type to me.
Normally wouldn't comment on design, but wanted to share some thoughts. It would be cool if the bullet would follow your for longer so that you can fire it far away and then use it to 'sweep' over other targets as it returns to you and you keep flying in circles. Another thought is how the same screenwrapping that affects the asteroids could play into that.
