Fun game! I got a score of 5,500! The game felt amazing but more importantly it felt fair. Often times bullet hell games focus on being overwhelming but you seemed to nail the strategy element of this genre super well. I also enjoyed the rotating gun mechanic, it was a great interpretation of the theme and a great way to constantly spice up the gameplay. My personal favorite was the one where it shoots out of the sides of the ship.
Overall, quality game! I can't think of anything that would really improve it!
