Very solid shmup experience! Art and sound are good, with some interesting animations and enemy variety. I also like the fact that the bullet movement has some variation, especially when your health changes. The only criticism I have is that after a while it becomes clear that you can "cheese out" by going up and down and spamming the bigger bullets when your health is low, so maybe it's something to adjust if you're looking to work on the game post-jam. Overall, good entry, well done!
