Shrapnel...my love
The action, visuals and controls (unless your mouse isn't very good or you're using a touchpad) are just so flawless!
I dig the blood effect where the more the bodies pile up, the more red there is on the wall starting from the bottom. That was kinda neat in my opinion. Another little thing I liked, was the attitude put in the character animation when firing some of the guns, particularly the lever shotgun. Of course it can get repetitive, but not that fast. Things get way too exciting for the repetitiveness to get boring. This is my favorite Thing Thing game over all.
