You are not kidding when you say "bullet hell", haha. That's a lot of bullets on screen! Great job on your first game! Things I'd suggest: the player ship acceleration could have a high end cap on it, so they would only ever accelerate at a certain speed once they'd reached it (sometimes I'd zip off screen really quickly), and the edges of the screen should probably stop the player since they can't see themselves and might have a hard time getting back into the action. I liked the addition of the blue bubbles; I was always looking for those to clear everything out :)
