I completed the game, it took me 20:02 and 192 hits.
Your take on the theme is very ambitious, I love that. And it's sustained by several cool bullet patterns, which makes the game fun to play.
Maybe it was the right decision to not implement a player death mechanics, it'd take a little more time that what players generally allocate during a jam to fully apprehend, this way we can get a good grasp of it by being able to deal with all the sequences the game has to offer, I definitely bruteforced a bit sometimes.
The game looks and sounds good too, overall a very cool project, congratulations, I can easily see this becoming a unique full fledged game.
