Oh wow, that's a very polished game! Love the silly theming. Not great at shooters, so it took me a while to get used to it, but had good fun once I did. While it's a small touch, I really like the "trace the loop"-segment allowing to refocus yourself.
One thing I will note is that while it was always clear when I was taking damage, it wasn't always clear to me why. With all the noise of the screen, bullets were very hard to see for me and I ended up utilising the "fly around wildly"-strategy instead of purposefully dodging them. Another thing I'd like is not to have to redo the tutorial loop once I've done it once, but that might just be me and my impatience.
Overall, though, hats off to you, very impressive game!
