original gameplay. You should try to set the stars colors depending on their depth instead of just random ( brighter = top = faster )

this is awesome! I have made a prototype with similar gameplay, but your version is really well done. =]

welldone and nice gameplay! the margin between death and life is very small though. maybe the player could have 3 lifes on start?

Very fun idea here and nice use of particles and things.
Wish it had some music and sound.
Hope to see more of it.
Good job.

Instead of lives I might suggest a short life bar and bumping off of other ships on collision with damage based on speed of collision.
Repair shops every ten stages perhaps or slight refill on collection of broken pieces from destroyed enemies.
Perhaps very little health with a rare drop of health restoring parts.
Less insta death but still a strong sense of danger.
