It's best that you either use the green wave or the yellow 5-way shot because in about mid-way through the stage, the rocket fighters can easily escape and are tricky to destroy unless you have these two weapons. The demonstration on how to do it is shown in my full 26-minute replay on YouTube:Kollision wrote:Cool!
How do I get the 100% on the 1st stage?
I'm quite sure I killed everything a few times and it always displayed 97%. And when I wasn't focusing I would get 98%.
So where's the catch?

This replay also shows how to safely finish off the final boss. I do not have strategical knowledge against him, but it's best to tap slowly left or right (you may need to pause to adjust your ship speed), or either create bombing runs on him (if you still have remaining bomb stock) in case you get pounded to the first level of your weapon.
