This "game" is exactly what it sounds like. You pick up chunks and toss them in an incinerator, you mop up blood and you stash money in a chest. That's it. I understand there's 2 to 3 hours worth of this tedious bull, but I checked out after 20 minutes. I regret even playing that long.
Do not play this game unless you find great joy in cleaning things. Even then, go offer to clean a friend's place, it'd be more productive and enjoyable.
