20 rounds done) I liked the graphics and sound design. It was pretty funny to play (especially blood prints after hit), but not fully immersive, cuz after using all the weapons you want something new, and you won't got it. This is monotonous a bit. I think the immerse may be increase by adding weapon state. It give'd reason to pickup other weapons from the floor. And I didn't totally inderstand the logic of the arc of dificulty. You spawn 2 enemies without weapon and one with the weapon on the round, but next round you spawn only one but without weapon... And maybe you should make more spawn points for enemies.
Though good work!
