This is easily, one of my favorite games ever made. It's a FPS and a Bullet Hell AND a Rogue-lite, which makes the game incredibly hard at times but an unbelievably satisfying experience. The guns all feel unique with some being unbelievably satisfying to use and I found myself spending far too much time playing it, eventually getting the full 100% unlocked. Play this one if you haven't, it's so cool.
