The game’s dead simple; the goal is to survive as long as you can. If things get too hectic, you can activate Bullet Time, which slows down enemy bullets long enough for you to navigate to safety. The highest rank is “Martha”, which requires you to survive for 3 whole minutes.
Making this reminded me of how much I enjoy shooters. I really should take a week out and make a more ambitious one at some point!
