The title is really clever, funny, and a nice twist on the theme! I got stuck for a little while at the pit with the spikes level until I figured, hey those body parts are coming off and you can pick them up but so far they haven't been used for anything and then I start clicking around and you can hold right click to aim and click to launch ur body parts at the levers. The body parts can also catch fire briefly but that mechanic wasn't used in a puzzle as far as I could tell.
This was after I tried to stack bodies with the saw until I noticed that bodies started despawning after you hit a cap.
