This was cute and fun! The controls were smooth and responsive, which is essential for a game like this. I also really liked flinging a bunch of bullets back at enemies, and learning their patters to time your attacks was really satisfying.
Sometimes enemies would spawn on top of me and start shooting right away, particularly the fairies that shoot a straight homing attack. It's hard to avoid them when they're right in your face, and its hard to tell where they are going to spawn. Other than that, the game was really balanced!
I'm not sure what the connection to the theme is, but I think this has a lot of potential if you wanted to expand on it for a future project/jam. Good job!
