There is a certain kind of zen-like satisfaction you get while playing this game.
Essentially you are nothing more than a janitor but while playing the levels you get so focused on achieving your task that you reach a state of mind not too different from bliss.

I'm not going to delve too deep into the gameplay as it is pretty much what you see in the trailer.
I never would have imagined how much fun it would be to painstakingly pick up random clutter, entrails and bullet casings, put them all into a bucket and shove that whole baby into the oven to literally watch it go up in (virtual) flames.

If you are looking for a cathartic experience in video games, this one is as good as it can get.
