Congrats on completing the game yourself! The visuals and music are great, and I really like the lore intro!
That said this game is REALLY tough! You've got good indicators for the boss attacks, but I feel like the player has too little health, especially since you can't aim where you shoot and have to get pretty close and personal. It seems like it being tough like your inspirations was a choice, but for future jams I'd consider making the content just a little easier. I think the player having a bit more health would have been a simple and effective fix here.
Awesome job, I can't wait to see more from you!
