really challenging game. imho health bar would help a lot and maybe some sort of healing items or zones. Also on screen shaking, as you are aiming on cursor, it starts to move a bit and it was really hard for me to hit the target :D but overall, I loved the idea of beeing able to fight them even without the gun, great job!
Oh, and sometimes I got killed either by my own bullets or by the gun I was throwing away, it was bit confusing
